Video Guide: Changing thermal paste(AS5) on Studio XPS 1645

[gpig]

The pads are to conduct heat away from the southbridge. Just put the pad back on top, and don't worry about it. The southbridge doesn't get hot enough to really worry about.

So the pad by the Southbridge and 4 pads around the GPU area don't have a similar effect to thermal paste, but rather act as "heat blockers"?

I've changed the thermal past in XPS 1645 (for Arctic Silver 5) and I'm not sure if I've done it right (especially for GPU - I've used the dot (for GPU) and line (CPU) method).

What should be the average temperatures (for Internet browsing, Office work) in XPS with i7-720QM, Ati 5730, standard FullHD screen for CPU and GPU?

~48-54C for both.

Thank you.

Then it's seems to be fine. Do you know what is the temperature after which coller starts working? This sound of starting and stopping cooler is quite annonying (and I suppose temperatures are some place aroung this level after which cooler starts working), especially when it does that every few seconds (it happens..).

And with cooling pad - is there a chance that these temperatures would drop even lower?

Fan low is 55C fan high is 75C. Yes, a cooler will drop your idle temperatures slightly, but it will drop your load temps more. I personally don't use a cooling pad (though I do have a fanless lapdesk).

Sorry, I missed this question. No, they do act as thermal conductors, it's just that the pieces they cover don't really get that hot, so small imperfections in the pads aren't critical.

I don't use those methods, I just can't get the results I see when I spread it myself (which in theory leaves bubbles and I guess is the reason people don't recommend this method).

The idle temps don't really tell you if you've applied it right.. just use furmark and prime to check the temps are in control when pushed. CPU is easy to get right but for me the GPU is harder and I've had to re-apply few times to get it right (idle was fine but push it and temps went up way too fast and high).

[andrew9]

They seem to be fine under load. I think they don't reach 75 degrees. I will check this later to be sure.

Right after I've changed the past I wasn't sure if I did it right because temp of GPU vent down a little but after that went higher (noticable). However this seemed easier then aplying it on CPU because GPU is small and I just put a little drop on it.

I still have some past left (together with Arctic Clean for cleaning) so I can do this again. But if the temps are all right it may be useless.



I have another question. I've had a really nice program for my old laptop - Inspiron 6000. It's called I8kfanGUI and it allows to change the setting of fan in computer. For example I can set it to start after reaching specific temperature.

It would be really helpfull in XPS 1645 (to make this temperature a little higher so the fan wouldn't start and stop so often) but I can't make this program works in Win 7 64 bit.

Is there any other program that would allow to change such a settings of internal fan in XPS 16?

i changed to Artic silver 5 when i replaced my mobo and got a hugh reduction on the temp.......

Anyone try Arctic MX-4 yet? I just ordered it and am curious to see what your thoughts on it are.
