2.0 out of 5 stars Flawed thermal design, December 30, 2013
By 
This review is from: Lenovo IdeaPad Y510p 59385820 15.6-Inch Laptop (Dusk Black) (Personal Computers)
First of all, this laptop is a BEAST, it is really cheap compared to other laptops with similar processing power, however there is 1 huge problem.

The chassis of this laptop was designed for 2x 650M VGA and because of this the 2x 750M are having heat issues due to the higher voltage and clock speeds. The built in main 750M is okay for most models (however many are factory defective and does not have thermal paste applied properly), however the Ultrabay VGA may be a deal breaker for many people.

The 650M in the Ultrabay can operate on relative acceptable temps (max 176F-185F), however the higher clocked 750M (and also the 755M) with higher core voltage will reach 208F in a matter of minutes and starts to throttle with GPU intensive games, like Crysis 3, Bioshock Infinite, Witcher 2, etc.

The reason for this is that the Ultrabay in this model was designed for 650M, which means:
a) The fan is too small
b) Technically there is almost no point where the fan could take in air, there is only a small hole at the bottom of the laptop
c) There is an aluminium casing inside, surrounding the Ultrabay slot which will eventually overheat and retain the heat

I have to note that even though the Ultrabay VGA reaches throttle temperature, the ultrabay fan will not start to work on maximum RPM, currently the only way to use the fans on maximum RPM is to use the dust removal service in the Lenovo software. Running the fans on maximum would help the ultrabay vga, but Lenovo does not allow it, probably because the laptop would be too loud and people would complain because of that.

Repasting the ultrabay vga will not do anything. A notebook cooler can help to lower the cpu and built in VGA temp, but it will not help the Ultrabay VGA, it only makes it reach throttle temp slower.

In short: A beast of a laptop regarding speed, however the Ultrabay slot is not designed to hold a 750M/755M and the VGA inside it will overheat with any game that utilize 99% of the VGA.

It is okay with games like Skyrim and X-Com EU, but Crysis 3, Bioshock Infinite, Witcher 2, etc will fry the Ultrabay. Please keep this in mind when you purchase.

Question: Would it be possible to modify the laptop's chassis and ventilation to ameliorate the heat issue? If so, how would be ideal?

I can't help but think that, if it were easy, the manufacturer would probably have done so already.

I am looking to use this laptop to run Adobe Creative Cloud. Do you think that would lead to overheating? And can the laptop handle running an external monitor?

Yes to both, this computer should be overkill for both of those applications

I haven't purchased this thing, but am strongly considering it.

That said, with the heating issues: I guess a laptop cooling device (with a fan) should do the trick.

If you read my review you can see that a cooler will not solve the issue of the ultrabay vga, because mostly the up, keyboard side gets hot, not the bottom.

Thank you for the response!

Completely disagree. I have been running Crysis 3, Bioshock Infinite, COD Ghosts, BF4....and I've never seen my ultrabay 750 get above 140F. This is with it just sitting on a desktop with no additional cooling.

My y510p, has dual 755M's they idle around 40 C (105 F) but running games like left for dead, it gets up to 85~90 C (185-194 F)
the CPU, i7 4700MQ idles around 50 C and gets up to 80 C while playing games, and that is with a cooling fan on the bottom. With Valley benchmark, got the GPUs up to 95 C and 82 C and CPU up to 82 C.

I seriously worry about the lifespan of my laptop if it keeps running at these temps. although there is no denying that it has beast specs, especially for the price.

Would this laptop work for League of Legends? Someone I know is looking for a laptop pretty much solely for League, so would this computer work alright for it? Or would the cons be too problematic for it?
