The Toshiba Qosmio X70 overheating / fan issue: Apparently, not so bad compared to other laptops

Toshiba Qosmio X70 Review, bottom open

Well, I’ve reviewed the Toshiba Qosmio X70 two months ago. The X70 comes with GTX 770M and a I7-4700MQ The caption was ‘too hot to be true’ and the reason for that assessment was that it seemed to me as a very hot laptop. There was another problem with the X70 that many customers reported and the problem was that it died very soon after you started using it (read) – mine had the same problem and just came back from repair. I don’t think the heating problem is directly related to this problem as I wrote and I think Toshiba fixed it with the new X70s that come out now, according to the reports on the X70 product page.

Now, the X70 is indeed very hot. The CPU can get hotter than 90C and gets throttled. The fan spins slowly and rather quietly even under full load. However, I’ve made some additional tests with Crysis 3, Borderlands 2 and Bioshock Infinite. All games were played on very high settings (described below) with Crysis 3 played on the same settings as notebookcheck ‘ultra’ for Crysis 3.

Drivers: 326.80 beta

GameSettingsFPS (avg)Throttling
Crysis 3‘very high’ preset, SMAAx223Yes
Bioshcock Infinite, gameplayHighest, except PP = ‘normal’31.5Yes
Bioshcock Infinite, benchmarkHighest (option 2)~38Yes
Borderlands 2Highest41-60Yes

If we’ll compare these results to the notebookcheck tests of several laptops with GTX 770M GPU, what we’ll see is that in Crysis 3 and Bioshock Infinite, the results are actually better than the laptops tested by notebookcheck. Bioshock Infinite is more interesting because the ‘benchmark’ is provided with the Bioshock game and is standard for all. Note that Crysis 3 was tested on 2 laptops and Bioshock Infinite on 5 laptops by notebookcheck. Here are the results for the GTX 770M benchmarks from NBC and in both games one of the tested laptops is the Asus G750JX which supposed to have better cooling system (and I believe it has). The Bioshock Infinite results are also better than GTX 675MX results of Anandtech.

That’s not the whole story. The Crysis 3 FPSs do not fluctuate a lot and generally stay around 21-24 constantly. Same goes for Bioshock.

The Borderlands 2 case is unclear to me. It seems to suffer more from the throttling, though still keeping a very high FPS rate. The GTX 765M from the Clevo W230ST review was doing better in terms of average performance, however, the minimal FPS with the Toshiba Qosmio is still better meaning you do get the benefits of the GTX 770M in that case also.

I might check more games, but the conclusions are that if there is a performance hit compared to other laptops – it is probably minor. Now, i’m not saying that I’m satisfied – there is obviously some performance hit in almost every game under full load and the fan throws out a really hot air to a point of not being able to use the mouse close to the right side of the laptop. However, when compared to the competition, you do get a very good competitor as far as gaming performance goes. Add to this the very comfortable (in my opinion) keyboard, the nice solid looks and the quite fan and you get a nice deal here. Usually you’d get the Qosmio X70 for $1000-$1200 (see updated deals here) and usually, compared to current competition, it is an option to consider.

Found away to kept qosmio cool. If you are playing a game with the backlight keyboard on then turn it off. If you turn it off you will hear the fan to speed up it is like the keyborad is taking power from fan, Just a though worked for me

Oh man , I still can’t make up my mind, the x70 being heavier and larger. How does it compare with y510p sli , does the 770m perform significantly better than sli 750 ? Also the y510p is cheaper I guess with Toshiba adding taxes with the prices. So my decision will boil down to whether 770m smokes 750 or not.

Did toshiba fix the “dying” issue with this series? i want to get this laptop but if it’s gonna die on me i would much rather prefer the sli y510p. Please advise.
BTW I prefer single gpu rather than sli.
