Thermal pad or Thermal paste?
hey there,
after some excessive amount of case modding to fit 4 additional suckholes/blowholes (3 in the side case blowing IN and 1 on top of case blowing OUT), i've finally managed to bring my case temperatures under control -- about 6C above the room ambient (ambient is 28C, case is 34C). But my case to cpu temperature delta has gone out of whack! previously with my case open and a floor fan blowing into the case, the cpu temperatures hovered about 18C above the case/system (when idle), but now it's a shocking 24-25C above the case temperature (currently 58-59C when idle). Thus I've decided to chuck the retail AMD HSF and get myself a Thermalright SLK700 cooler. Now that the backgrounder is done with, my actual question: should i use thermal paste instead of a thermal pad with my new cooler? I've read that AMD will void your CPU warranty if you use thermal paste/grease. Also would thermal paste require any maintenance, like removing, cleaning and reseating the cooler every few weeks? thanks, vin |

Use paste for best results. Commercial pads are said to be pretty good-
but impractical for small purchases. Go with Arctic Silver Ceramic- best combination of performance and novice-safety. BTW- Some say it's bad etiquette to cross-post. Choose one group at a time. -- Valid spambot resistant address: deanATyniDOTnet |

I agree with Rick, and I only use thermal grease. It lowers the temps
substantially. A couple of weeks ago, I had to have a CPU replaced by AMD, they did so without any problems. AMD is an excellent company to deal with. Artic Silver has instructions on their site as to proper installation of thermal grease. Minimal amount spread to the thinnest film is the secret to best temps. I don't use Artic Silver though, rather I use some that came with a Dr. Thermal heatsink. Having said that, your CPU should not have risen more above the ambient temp of the case. Did you remove the Themal material, clean the residue with isopropol alcohol and replace it with a fresh one? I would also check your mounting of the heatsink and the clip tension. A rule of thumb is that with the heatsink rests at a similar temp above the case, and 24C is too high. Look for 10C when idle and 15C under 100% use, this will depend upon the effectiveness of your heatsink, and mounting. Alan "Rick" wrote in message ...

i've read the thermal paste installation instructions on the AS3 web site.
the thermal paste installation is quite detailed and helpful, but i'm quite confused about the cleaning of the cpu core/ceramic bit (cleaning the old heatsink doesnt apply to me, as i'm replacing my stock HSF with the thermalright 700) how do i safely and properly clean the thermal pad residue from the cpu core/ceramic? i checked with my local chemist, but he doesnt have any isopropyl alcohol with him. also it's mentioned that if i use any other cleaning agent, i'd still need to do a final cleaning with isopropyl alcohol -- are there any other commonly available cleaning agents that i can use? another thing, do you directly dab a tissue paper with a cleaning agent and then rub away the residue from the core/ceramic of the cpu? or would a cotton bud be preferable? thanks, vin "Alan" wrote in message able.rogers.com...

First you need to scrape off the thermal material, DO NOT USE A METAL
OBJECT, as this will scratch the surface. Plastic is better, and take your time to be very careful. You must not scratch the chip surface or the heatsink surface. I have Isopropyl to clean remaining residue and remove any oils, so that is what I now use. I cut small pieces of paper towel and use them, (oil free and doesn't leave particles) Before that I used a very slight amount of cleaning fluid (varsol type) which is absolutely not recommended. However I was extremely careful and made sure there was little to no residue left. Of course this is an oil base, so it is not perfect, but it did work. I have read in a newsgroup of people using things like goop-off and orange citrus stuff, I believe these are not recommended either. Others have used nail polish remover or acetone (they are same base), I absolutely say NO to that, acetone will melt certain resins and damage the surface.

Also would thermal paste require any maintenance, like removing, cleaning and reseating the cooler every few weeks? thanks, vin A dissenting opinion. You've made significant changes to your case airflow, and achieved a reduction in *case* temps with increased CPU temp. My first thought is that you've mounted a fan(s) where cool air is blowing directly onto the motherboard "case" temperature diode, while disrupting proper flow of cool air to the HSF area. If you've managed to create a dead air area around your CPU (quite possible if you've added a lot of inflow without adequate exhaust near the CPU/HSF), it's your mods that have caused the CPU temp increase. I'm offering this because you imply that you did nothing with your current HSF while doing the case mods, correct? If that's true, there's no reason to believe anything *but* the case mods affected the CPU temperature. If I'm right (happens occasionally), you're going to be disappointed with the new HSF, as no HSF can work efficiently if it's being fed hot air. |
