After messing my CPU up with clumps of thermal compound i have to start again with new thermal compound... :( :mad:

so im wondering which is the best to use for the CPU i used Akasa AK-455 which to me when it arrived!

didnt look that good with only 1.5grams and no lable on it, it could have been anything...

so whats the best thermal compound to use ?

thanks

A test made by the russian OC team itc/modlabs; AS5 and ASC are identical in performance, and are, and AS5 is terribly overpriced for the performace it offers:

Shin-Etsu MicroSi MPU-3.7 is meant to be really good. I believe w3bbo is using it and is finding it extremely good.

Yes I do, but the cannot be mentioned on here as they are a competitor.

Though it is out of stock and they seem to have no ETA for it as it is very hard stuff to get.

ah i see thanks anyways, and toothpaste.... :rolleyes: are we talking about THE tothpaste

? ? ?

Haha
 
Toothpaste is actually quite good until it turns into a solid which will be in quite a short time.

Artic silver 5 or ceramique are both as good as each other really - I tend to use as5 on IHS but ceramique on bare silicon. I recently made the switch to shin-etsu.

Testing @ 3.7ghz 1.45v
Ambient temp of 18c for the AS5 - 20c for the shin-etsu.
I didn't feel the need for multiple mounts as mounting a d-tek fusion is idiot proof tbh and very difficult to mess up aslong as you tighten the thumbscrews diagonally 1 turn at a time.

Temps before (Arctic silver 5) = 44c Full load (after 12hrs Large FFT's)

Temps after (Shin-Etsu) = 41c Full load (after 12hrs LargeFFT's)

A nice 3c drop on load, also bear in mind the shinEtsu was working with a higher ambient temp and has not had the '200 hours' AS5 suggest for 'setting'.

An impressive drop for £2 imo.

The compound itself though is a pain to work with. Its not at all like AS5 which incidently isn't exactly a dream to work with either. This stuff is more like a 'paste' than a 'liquid' therefore the spreading method(via razorblade) which I prefer is a little more difficult to get a thin layer as it seems 'drier' than the as5.

Temps though speak for themeselves so I would go with it over As5 and will do so in future builds aslong as its available.

There is however NO mention of it not being conductive/capacitive so I would assume it is. No squirting it all over the motherboard then I guess :rolleyes:
 
:eek: Hope you dont plan on using your heatsink again if you ever remove it and for that you might need an angle grinder!
 
I use Arctic Silver 5 on my CPU's. Last time I removed the heatsink from my Athlon 64, the processor came with it, had to use a knife to remove it. At least it doing it's job properly.

Toothpaste! And Vegemite (As in Marmite type stuff!)! Those are new to me!

And no one mentioned Thermaltake's The Chill Factor. I swear by this stuff. It can keep my X2 4600+ as low as 25°C! It's as good as, if not slightly better than AS5. Plus it's cheaper/you get more. I swear by this stuff now. OCUK have it in their Thermal Compounds section.
 
Arctic Cooling MX-1 seems like its good value stuff, shocking thing is i have tons of it lying around since i build machines it comes standard with the arctic cooling heatsinks i use on the machines.

didn;t know i was sitting on a gold mine. :eek:

and i never used the stuff since it comes out all hard and seems difficult to apply. :eek:

Thermaltake's Chill Factor is indeed excellent for the money.
