Windows 7: Timing for thermal paste renewal

26 Nov 2012   #11

Windows 7 Professional 64bit SP1

If you used a good quality thermal paste originally, there is no need in changing it unless you remove your CPU cooler. Just take your PC outside and hit it with some compressed air and a microfiber cloth for smooth internals, do not dust anything with a PCB with the cloth though, just use it for the power supply, case structure, drives, etc. Use the air and focus on fans and heatsinks as they usually collect the most dust and that will raise temps quicker than anything.

I did a dust clean using a can of compressed air on the PCBs and cooler fins - gently. Cleaned the dust on other surface with a cloth and vacuum cleaner. I think this was just to be tidy. Most importantly I took off the case front, removed the intake filter and gave them a good clean.
Temps dropped around 4 Celsius when all cores were flat out.

It is a bit hard to give the cooler fins a really good clean without removing the cooler and needing to reapply thermal paste when refitting. I didn't do this because I'm lazy - or is it I'm efficient.
I still think the thermal paste does dry out or loose its effectiveness over some time.

Thanks for the inputs.

That's a fair temp drop Michael. I like the vac method because the fan is blowing air in the fins and pulling the dirt in reverse direction seems logical.

Lady F, I have read about static with vacuuming too. I ground myself to the PC case, touch it, and have no far.

I'm a coward so I'll stick to blowing air. I don't let my computers get dusty enough that getting the dust out is a problem (again, because I'm a coward).

Thermal Paste Expired?
So I put together the PC about a year and a half ago. I recently got into overclocking, and wanted to re-apply thermal paste on the cpu to try and see if it would help temperatures. I think I have a decent Haswell 4670k chip for overclocking, as earlier I was able to get a stable 4.7ghz overclock...

Which thermal paste to use on laptop
I have a Toshiba L550 laptop running 64bit 7 on with an i5 430M and have already put in 8GB RAM and just about to slip in an M4 Crucial 128GB for speeding it up. I would like to swap out the 430M for a i5 560M and the manual tells me to use Shin-etsu thermal compound. Now apart from...

Thermal Paste
After reading some good reports on Shin Etsu thermal paste, I bought some, but am having a lot of problems with getting it to spread properly. It tends to clump together, and when forcing it out, it leaves such a thin covering that the lettering on the CPU is still plainly visible. I'm about to...

Thermal paste
Hey guys, So I was hoping to get some clarification (as well as personal opinions) on thermal paste application. I have heard many different ways of applying thermal paste, and I am guessing they all work. The real question is, how MUCH? I just have a feeling I put on TOO much on my new...

Used way too much thermal paste
This isn't that important, all it is is that I'm worried. It was my first time round putting thermal paste onto a cpu, and i sort of used an entire 3.5g syringe of arctic silver 5 underneath a zalman9700. Yes some did come over the sides, wiped it off, I'm guessing there is a layer inbetween...
