T61P overheating

Oh hey its me Been a while since I've last posted

Anyways, every now and then when I go and feel the bottom of my laptop, it is hot. Temps are in the 60's and 70's when charged and idle.

I just got the laptop back from lenovo after getting my GPU fixed (got my keyboard, keyboard bezel replaced) so I assumed they must of cleared all the dust and debris in there.

Nope still hot as hell in there.

Do you think its worth me opening up my laptop and perhaps replace the TIM and just do a second inspection?

 

that is bit high, i think the heatsink needs to be replaced.

While they may replace the motherboard, they do not always replace the heatsink, unless it is making some sort of mechanical grinding noise.

 

i should of say the fan, sorry a typo on my part. The fan and heatsink is an integrated unit, so they are replaced only if the heatsink don't transfer heat adquately or the fan is not working properly (i.e. making the grinding noise).

 

I am not sure how the depot people gets paid by IBM or Lenovo for their warranty service, but the continuation of tenure as a depot, requires that they minimize the cost of service. i.e. replace only the part that is required. Otherwise, the depot would make all sorts of wild claim regarding parts replacement to maximise their claimable fee.

Obviously, if the depot was directly owned by Lenovo or IBM it would not have the same problem.

 

Anyway, you can re-apply the thermal paste and it should help if not solve the issue. My 7 yr-old ThinkPad has a barely spinning fan, it was never replaced and is rusty as hell now. Still after applying an aftermarket high-end thermal paste I reduced the CPU temps by 15C.

 

if you reapply the heatsink with your own thermal paste, this will void any remaining warranty on the T61p

 

I'll give Lenovo a call tomorrow to verify this once and for all. Have seen quite a few posts about people replacing the paste on their own without voiding the warranty.

 

Hi guys, I have a 3 1/2 years old T60P and recently replaced the heatsink. I use the original thermal paste that comes with the new heatsink on the GPU and northbridge and apply Arctic Silver5 on the CPU. The temp. on the CPU are measured around 50's( which is around 15 degrees lower than before) and 70's on the GPU( with factory thermal paste). My question is should i apply arctic silver5 on the GPU too.

 

What you have to be careful of when replacing a thermal pad with thermal paste is that the contact between the copper heatpipes and the GPU surface is still good - thermal paste is typically much thinner of a layer than a thermal pad, so you may need to make some additional modifications if you're going to the place the factory stock thermal pad.

 

Yes, and normally, it's recommended not to replace pads with paste. The paste can bleed and create a mess on the mobo, since you have to apply a generous amount to eliminate the gap. The pads are there for a reason. Ideally, you'd want to substitute them with a copper plate (of a precisely needed thickness) or with higher quality pads.
If still wanna try a paste, use a NON-conductive and NON-bleeding compound (such as MX-3, ICD7/24 etc).

 

thank you guys! sounds like a lot of works. Is 68 - 75 degrees GPU ok on the 14" T60P?

 

For a GPU, that's not too bad. But is that idle or at load? Make sure your load temperatures do not get past 85-90 degrees.

 

i havent had chance to stress my T60p lately. I do all my 3d and graphic work on W510 now. i only use the t60p as a backup and internet download machine now. 70 degrees is the idle temp.

 

Have you done any cleaning or heatsink mod to your T60p yet?

 

70 idle is not acceptable. You should clean the vents/HS and maybe even replace the stock thermal pad with the high quality one.

 

I wouldn't say that, brushless fan motors are expensive, i don't see why they would replace it everytime it needed service.

 

thanks for all the answers +rep to all

 

Before i replace the new heatsink, i use the super high power hand dryer in my office to blow all the dust on the system board. And i use the cleaning solution that comes with the AS 5 to clean the CPU, GPU and northbridge.

lead_org: What is heatsink mod?

Last night i finally have chance to play video game on my T60p and the GPU reach 104 degree (tp fan control). I heard on some forum suggest that the tp fan control might not be accurate.

May be i shouldnt use my T60p to play game anymore!

Cheers

 

What kind of high quality thermal pad should i get?
