So now that I have had my laptop for a month or so, I have noticed a few things with it. For instance, when it's been running for a while and it heats up, I tend to have glitches on video and audio playback. So this made me decide to check my temps.

At idle, they aren't bad....but when running Prime95 alone, my cpu will heat up to around 83 degrees Celsius. When I add a graphics card burn in running with Prime95 the cpu will heat up to 93 degrees Celsius and the GPU will get to around 88 degrees Celsius.

Now I understand that Mobile chips are designed to handle a lot more heat, but doesn't this seem a bit high? Should I consider taking off the heat sink and replacing the thermal compound with Artic Silver 5?

Any advice is appreciated.

It's only been a month, so I doubt dust is an issue. Chances are, they use silpads or reinforced compound to make the thermal connection. Can't hurt to redo it. Also, check the fan. We have some s10e netbooks from Lenovo, been put through some abuse, and the fan bearings are giving out.

The fan is pushing out very hot air just fine. I'm kind of staring to think that the heat sink design just isn't good enough to handle a i7 processor and GPU with just one fan.

yeah, that's not a lot of area on those fins, but that's a good fan, probably pushes air pretty hard to make up for it.

Can't hurt to redo the thermal interfacing if you already have the grease. You have some stuff to clean the old gunk off with?

Also, be sure to follow the recommended tightening order (1 to 6)

I do have this stuff....

However, I don't know where it's at. I do know that rubbing alcohol works ok...

As for having some
35-100-007-TS

I don't have any on hand right now. I might order some in a week or so though.

Now as for the recommended tightening order...I'm honestly not sure what it is.

It's just the numbers on the "legs" of the heat blocks. And that solvent kit is the same stuff I have too.

Right, my daytime job is fixing latops and mobile phones. Ive fixed countless lappys with heat issues.. 83 is far too hot. There is usually a matte of hair where the fan meets the fins of the heatsink, even after a month. Do what others have suggested here, some lappys run hot, the hp range got recalled for overheating...ive fixed loads of the hp ones, they were all getting the random bsod's youve mentioned.

You might need to re-paste the CPU/GPU.. Get some Shin-Etsu MicroSi G751 or Tuniq TX-3, it has one of the best thermal conductivities for paste.

Sometimes manufacturers do sloppy jobs :( Even for ASUS laptops, but mines still runs cool. I have Starcraft II on ultra settings and handles just fine.

No hair...no dust...Perfectly clean from what I can tell. That picture is from today.

Sounds like you simply have a hothead on your hands

I agree...I don't think that the heat sink was properly designed to handle both the ATI Mobility Radeon™ HD 6570 and the i7-2630QM processor at the same time.

You only have 1 fan for both the CPU and GPU? Wow, that's a pretty terrible design.. Have you opened up the rest to see if you have another fan? Those processors are high end and will generate a lot of heat! I'm surprised Lenovo would only have one fan for both..

I'm not surprised at the single fan, but I am surprised at the small fin stack. ALso, they tried to increase the surface area with some sort of spray-on stuff instead of anodizing? Even my Dell 1505 with a T2500 and GeForce Go 7300 has twice the heatsink stacks...

I have confirmed that there is only one fan. Also, like I have said before, that picture is of my laptop. No trickery going on here. :)

I can get close ups if you'd like.

I noticed that too. I'm not sure what kind of coating it is. I do know that anodizing has pretty poor heat transfer. I'd rather them just leave it as pure copper.

I am also curious if some of the fins go into the fan.

I'm sick and tired of my temps.....
Replacing the compound tonight.

While playing the new Battlefield 3 Alpha trial for 15 min my temps looked like this.
Check out the max temp.

Are you using HWiNFO32/64 getting those readings or was it a stock application?
