MSI GT780DXR review

September 23rd, 2013 No comments

The GT780DXR is, as the “GT” characterization rather hints, a actual sports car of the laptop apple – with a big engine, and abundant balance for some full-on carriageable gaming. Equally, as it packs some austere accouterments it’s additionally appealing chunky, and one of the hardly beneath carriageable notebooks you’ll anytime appear across. But that’s to be expected…

Chunky notebook

The assemblage is appealing heavy, belief in at aloof Fujitsu Lifebook A6110 cpu fan a blow beneath 4kg, and appealing beefy too, decidedly appear the aback of the laptop, area it widens to angle 60 mm alpine if you accommodate the little elastic feet.

And accustomed this chunkiness forth with a rather apparent atramentous finish, the 780DXR is absurd to win any awards for its aesthetics. On the upside, the apparatus is sturdily complete and faces no body affection issues.

Once the laptop is opened up, the aesthetics are analogously boilerplate – we weren’t so agog on the argent fine-mesh apostle grilles, for example. However, this absolutely is a apparatus which isn’t anxious with form, but function. That activity actuality accelerated anatomy ante and gaming, of course, although some facets of the architecture are anxious in agreement of the gamer’s needs aloft fast and aqueous action.

Primarily, we’re talking about the keyboard which has been advised by Steelseries. It’s a nice and ample abounding keyboard, with well-spaced chiclet appearance keys. The activity of the keyboard is absolutely clicky, but it provides a solid and affable accounting acquaintance on the whole. The blueprint of the keys has additionally been hardly adapted from the barometer to account gamers.

The spacebar has been confused over to the larboard a bit, so it, the Ascendancy key in the basal larboard corner, and the WASD keys anatomy a triangle. In added words, it’s adequate for the larboard duke with the acceptable ballista ascendancy arrangement – which is a nice touch.

The hardly confused spacebar didn’t affect our accounting accurateness at all, and in actuality our alone abomination with the keyboard was annihilation to do with the adapted blueprint on the larboard side. In fact, it was the Enter key on the right, which is one of the abate arrangement sometimes begin on laptop keyboards. That meant we absent it occasionally, but not so abundant to be absolutely irritating.

Furthermore, the keyboard allows for assorted accompanying key presses (over ten of them), and MSI provides a acceptable gaming abrasion forth with the GT780DXR. The own-brand abrasion has programmable keys, and a 3200 CPI resolution that you can about-face on the fly for aback zooming in with that assassin rifle. Thus gamers are appealing able-bodied able from the get-go with this notebook.

Anti-glare display

Naturally, the axial allure isn’t the acknowledging peripherals, but the amount blueprint – the display, processor, and the cartoon agenda abetment it Fujitsu Lifebook E8410 cpu cooler up. Fortunately, it’s all acceptable account on this score, too. The 17.3in awning is a abounding HD 1920 x 1080 affair, and it’s a aciculate affectation with an anti-glare coating.

The trend afresh has been appear bright screens with gaming laptops to ensure active colours, but they additionally ensure rather beneath acceptable reflections in brighter environments. With this MSI notebook, aback sat in a ablaze allowance you can be assured you won’t accept to beam at your own mug during darker gaming or cine scenes. The anti-reflective awning is a actual acute boon, but the best allotment is the colours still abide active and able-bodied balanced. Blu-ray movies looked decidedly impressive.

In agreement of raw firepower, the 780DXR comes able with an Intel Amount i7-2670QM, a cloister amount barbarian which runs at 2.2GHz, with turbo up to 3.1GHz. That’s backed up with a able adaptable cartoon solution, the Nvidia GeForce GTX 570M with 1.5GB of video anamnesis on board. 8GB of arrangement anamnesis is provided.

As you ability imagine, this aggregate meant that the 780DXR performed impressively aback we benchmarked some games. Battlefield 3 ran actual calmly on aerial capacity at abounding HD resolution, averaging 40 fps (frames per second). Cranking the cartoon settings up to ultra detail, the apparatus still maintained a playable 30 fps on average, although it did dip to the mid-20s (and sometimes low 20s) aback the activity got blubbery and heavy.

Dusting off our brand and shield, Dragon Age II on abounding HD, with actual aerial details, hit an boilerplate of 35 fps slowing to about the 30 fps mark with abundant action. Again, that fabricated for some attractive attractive cartoon abounding forth appealing smoothly. The Stalker: Call of Pripyat benchmark, active at ultra details, averaged 70 fps, and 35 fps on the accelerated “sunshafts” section. That’s a actual acceptable Fujitsu Lifebook S6110 cpu cooling fan aftereffect for a laptop.

Suffice it to say that gamers won’t be aghast with the achievement here, or the accomplished affectation which makes the best of those college beheld detail settings. MSI additionally has a TDE “turbo” button, which adds an added few frames per additional to a game’s alteration aback pressed. There’s additionally a fan button to about-face on added cooling for aback the laptop is actuality pushed adamantine apprehension 3D graphics.

Fan noise

Bear in mind, though, that the added fan ability is appealing abuse noisy, and can be heard aloft the speakers angry up full. Indeed, the absence fan acceleration is audible, and a blow noisy. Heat levels aren’t bad – but as you’d apprehend with a apparatus packing this arrangement of cartoon firepower, the abject does get somewhat balmy aback gaming, but not to a ambiguous degree.

MSI’s assignment on the sonic ancillary is about as absorbing as the aqueous visuals this apparatus provides. Twin Dynaudio speakers are backed up by a subwoofer, and this amalgamation absolutely delivers some appealing appropriate bass depth. Accoutrements and explosions account from some absolute impact, and the aggregate can be cranked appealing abundant up to abounding with little or no baloney evident.

The complete has a accurately rounded, apple-pie feel to it – so for archetype in the acclaimed Matrix cine “gunfight in the auberge lobby” scene, the bass guitar of the music clue can still be heard over the babble of apparatus accoutrements and exploding masonry. Acceptable stuff.

In agreement of ports and extras, there’s a acceptable array. The laptop boasts a leash of accepted USB ports, two USB 3.0 ports, an e-SATA port, VGA and HDMI, forth with a multi-card reader, Ethernet port, microphone, headphones and band in. An HD webcam is additionally on board.

There’s no SSD here, and while that absolutely would accept been a acceptable addition, it would accept pushed the amount up, too. The acceptable account is the 1.5TB adamantine deejay is abrupt enough, and provides affluence of accumulator space.

Finally, we appear to the battery. We activated the apparatus to see how continued it’d aftermost arena an accelerated bold abroad from the mains, with counterbalanced ability settings. The GT780DXR managed 1 hour and 45 minutes, not a acceptable result, but not a abhorrent one either because this is beneath above load.

However, it’s additionally account acquainted Fujitsu Lifebook P8110 cpu fan that anatomy ante biconcave from actual bland in Battlefield 3 with aerial details, to actual hasty aback active on the battery. MSI’s anthology isn’t decidedly blessed abroad from the mains, and throttles aggregate back, which underlines its role as a desktop backup model.

Verdict

The GT780DXR is a bit bulky, not abundant to attending at, and it doesn’t book able-bodied abroad from the mains. The fan is additionally a bit noisy, decidedly aback it bliss up a gear. However, we accepted this notebook’s affection anti-glare affectation and aqueous anatomy rates, not to acknowledgment some acute added touches for the gamer, such as the keyboard architecture and admittance of a appropriate gaming mouse. This MSI laptop is a aces shop for because what you’re accepting here.

Has Liquid Cooling Killed the Heatsink star?

September 19th, 2013 No comments

I’ll be honest, afore alive for Antec, I anticipation of Aqueous CPU coolers as a bad idea. I mean, Really? Liquid. In your computer? Why not aloof being chewing gum in the optical drive? Something about it aloof did not sit appropriate with me Lenovo Ideapad Y560 cpu cooling fan. But back I congenital my fresh gaming PC aftermost month, a aide absolutely pushed me to install a Kuhler H20 620 for my fresh Intel i5 2500K, so I went with it. Let me say the affair was a dream.

But actuality is the question: Are aqueous CPU coolers the beachcomber of the future? Or are they aloof a novelty?

Previous ancestors of aqueous CPU coolers

Understandably, bodies are apprehensive of aqueous CPU coolers. Aboriginal off, aqueous and aerial achievement PC electronics about do not mix. So there is some attrition there. But alike added is the actuality that aqueous cooling technology is aloof now communicable up. Its seems that the aboriginal bearing of aqueous CPU coolers larboard a bad aftertaste in people’s mouths and accept fabricated it difficult to to accept this fresh technology.

Why?

Previously, aqueous cooling technology was, well, not effective. The cooling achievement was bound and the amount was acutely high. The systems were complicated and difficult to install while the pumps were anemic and abounding bare to be army alfresco of the computer case. In abounding ways, aqueous cooling was added of a gimmick; a way to pimp your gaming PC, attending air-conditioned and affect your friends. Anyone who knew, would never accept advised them to be a applicable battling to the archetypal CPU heatsinks we grew up with.

New technology brings aqueous cooling into the mainstream

But as with all technologies, already aqueous cooling arrangement got the adventitious to assignment through their growing pains, what emerged was an astoundingly acceptable product, ideal for high-performance gaming PCs. Lets use my acquaintance as an example. Back architecture a PC two months ago in the Antec office, a aide apprenticed me to install the Antec Kuhler H20 620. Like others, I was a bit leery. Aqueous cooling against a accepted heatsink? Do I absolutely charge it? What about accession and refilling? What about ability consumption? And would it alike work?

Well, I can say that it installed absolutely actually in a few Lenovo Ideapad S10 cpu fan account and today it makes about no noise., nor accept I apparent any apparent access in my ability consumption. Perhaps best importantly, I can abridge my aqueous acknowledgment achievement this way: I run my PC on ultra aerial settings, arena Shogun Total War 2 for hours on end, yet the air advancing out of my bankrupt admirers is ice cold. That’s right, the Kuhler 62o has angry my gaming PC into an air conditioner. I couldn’t be happier.

But this is aloof he tip of the iceberg. Back you attending at price, aqueous coolers are absolutely closing the gap. Consider Antec’s Kuhler H20 620 that sells on Newegg for $62.99 to the Thermaltake Frio Overclocking CPU acknowledgment that amount $65.00. Back you see prices like this and buck in apperception the bigger achievement of aqueous cooling in accepted (no amount what cast you adjudge to buy), you absolutely accept to admiration why the CPU heatsink still exists?

The aboriginal CPU acknowledgment I anytime installed was an AMD advertence HSF back I upgraded my Athlon XP processor to a above model. It was in actuality my aboriginal anytime PCupgrade. I bethink anxiously Dell Inspiron N7010 cpu cooling fan (and conceivably a little nervously) agreement the blocky aluminium heatsink in position, hooking both abandon about the socket, blame the assimilation arm bottomward and thinking, “hmph – that wasn’t so hard.”

A brace of years after and I was architecture my aboriginal PC from scratch. Actuality an ardent clairvoyant of Custom PC, the Elite Account was my afflatus for basic selection. The Arctic Cooling Freezer 7 Pro was the alone choice. This was the aboriginal time I’d encountered push-pin arrangement acclimated on Intel’s advertence cooler. While the assumption seemed simple enough, my abridgement of PC acquaintance and agitation to accomplishment the body ensured that it was appreciably added difficult than it bare to be. Nowadays however, actuality accustomed with the nuances of the simple system, installing a acknowledgment that uses it takes about eight seconds.

But there are some CPU coolers that use accession methods that absolutely addle the mind. I generally allegorize these ascent systems to Meccano sets; such is the applesauce of the apparatus list. If these coolers provided a CPU acquaintance that affiliated to albatross sitting on the heatsink and alarming achievement to cossack again I’d understand. But abounding of them don’t. Even if they did, absolutely CPU acquaintance could be accomplished in a simple manner?

One that springs to apperception is the Zalman CNPS 10X Extreme. It requires a back-plate to sit abaft the motherboard, a ascent bracket which sits on top of the motherboard, a hold-down to defended the acknowledgment to the ascent bracket and, to authority the caboodle together, a apparatus shed’s account of screws and bolts. What’s more, you absolutely charge to abolish the fan to accumulate the Meccano set HSF as contrarily you wont be able to ability the screws. Because of the way a fan ambassador has been congenital into the fan mount, reattaching the fan is a nightmare. What’s more, the achievement numbers are pants.

The Thermalright Ultra 120 eXtreme – ascent an HSF Dell Latitude E6510 cpu cooler doesn’t charge to be any added complicated

Let’s booty a attending at the Thermalright Ultra 120 eXtreme for some comparison. A back-plate and a authority bottomward are required. Four spring-loaded screws catch the base-plate in amid and the fan clips on in a second. Job done. What’s more, the cooling is awesome.

Why accomplish it added complicated? Is it because some manufacturers are anxious bodies will feel gypped if it doesn’t booty 30 account to install? Have they active ex-Meccano engineers who are badly aggravating to re-instate their abilities in the apple of HSF installation? Feel chargeless to allotment your thoughts and adventures below.

Laptop CPU cooling fan failure Grand Collection

September 17th, 2013 No comments

The main function of the notebook internal firmware is to dissipate heat emanating out, if the CPU fan fails, such as CPU fan does not turn up or turn very slowly, because the notebook will not distribute the heat inside out, leaving the notebook Samsung R700 cpu cooling fan Firmware temperature rise Laptop crashes blue screen appears high imagination. Thus ensuring a good CPU fan rotation can guarantee the normal work performance notebook, the following is the author collected some CPU cooling fan failure, for your reference.

1, CPU fan stops lead to crashes

Symptom: Laptop CPU fan sometimes stops turning, causing the CPU temperature is too high and crash.

Troubleshooting: The current mobile CPU basically has a temperature protection. When the CPU temperature exceeds a certain limit, it will crash or reboot, thereby protecting the CPU. If the CPU fan problems, it should be repaired as soon as possible in order to troubleshoot and ensure the normal operation of the fan.

2, CPU fan installed in place leading to frequent crashes

Symptom: A IBM T42 laptop, just start after running for some time will slow down, but there is no reason to panic and automatic restart of the phenomenon.

Troubleshooting: Since the noisy, after the laptop CPU fan had been dismantled done clean. Therefore, to determine the problem may be the CPU fan, CPU temperature is too high and cause problems. Laptop apart again see, it really is the original T42 CPU fan screws are in place, and then reinstall the fault does not appear. Failure Comments: If crashes and restarts, and not due to the virus caused by improper use, it may be caused by the CPU temperature is too high. If the laptop’s CPU cooling fan cooling effect is not good, leading to operating temperature is too high, it may lead to frequent crashes.

3, CPU cooling duct blockage caused by downtime

Symptom: a Lenovo laptop sun 420A, start working more than one hour after the sudden shutdown, after a while can be switched to open one would then stop.

Troubleshooting: Since the system is not able to boot instructions hardware problem, probably due to the CPU temperature is too high, automatically open the protective function and downtime. Open laptop computer to check and found no problems open cooling duct and found duct blocked by some fluff items (shown), to clean up after the laptop recovery, troubleshooting.

4, notebook computer’s CPU fan rpm stop

Symptom: Toshiba M2 laptop, in use for some Samsung Nc10 cpu cooler time and found the CPU fan sometimes turn sometimes does not turn, but the feeling body temperature has been high.

Troubleshooting: The laptop fan is the use of temperature control design, the general CPU temperature is higher than 70 ℃ only when rotated. Body temperature is high does not mean that the internal temperature is really high.

5, laptop CPU fan has been rotated

Symptom: a laptop computer, the fan is running normal programs (such as Word, browsing the web) when five minutes transfer time, duration 5 to 6 minutes. If you are running the program is too large (such as 3DS MAX) will accelerate the rotation have a great noise.

Troubleshooting: This is a normal phenomenon, the laptop fan is temperature control design, only reaches a certain temperature will rotate, some with AMD processor-based notebooks, the power consumption is relatively large. Therefore, the frequency of rotation of the fan will be higher than on other models, during the big game on a more normal rotation.

6, the notebook computer’s CPU fan does not turn

Symptom: a laptop computer and found that the CPU fan to the back panel of the computer is running very high temperatures does not turn, then suspect the CPU fan is broken. Later it was found when the computer starts self turn about, the fan is no problem with the brake on. But do not understand why in the back panel under high temperature still does not turn.

Troubleshooting: CPU CPU cooling fan is mainly for only when the CPU temperature is higher than 70 ℃ or so will rotate its heat. In addition Samsung R428 cpu cooling fan, the back panel temperature problems are not necessarily caused by the CPU, hard drive, memory, graphics cards and motherboards and other parts of the heat is likely to gather here, so the back panel temperature and CPU fan is rotating necessarily linked. In addition, it is recommended to run the big game to test, if the period of time the CPU fan not turn, there may be a problem of CPU fan.

Deal with the problems of the CPU cooling fan to make the notebook work properly. So when we buy laptops, notebook configuration issues in considering must also consider the laptop CPU fan cooling performance, this notebook’s life will be a little longer.
