Should i reapply AS5?

Hey everyone, i bought AS5 to use with my stock cooler (bc i used all my money on my parts instead of a e2200 and zalman 9700) and i haven't noticed a drop in temps except for idle. I applied it by putting a dab in the middle, and then squashing it with the HSF (when i relocked it). I went on the arctic silver website, and then looked in the instructions which said that i should make a line across the middle. So i am wondering, should i reapply it or not?:confused:
 
After the breakin time see how the temps are before simply rushing to reapply. If you used too much or too little the temps will be up somewhat then seeing the need. The initial temps seen will be a little high as expected as long they are down under 35-40C idle without ocing you should see that drop even more. Above 45-50C defintely a need to reapply.
 
AS5 also recommends a cure time that alternates hot/cold, correct? That means don't leave your system on for 200 hours at once. Run it for a day, then shut down, run, then shut down. This will allow it's mojo to take full effect.
 
On the first day or so the usual recommendation is to let the system warm up for about 3-4hrs. there and then shutdown and let it sit overnight. That helps to start the bonding/heat conduction process. It usually takes a few days after to see temps start to drop into their normal range. To see a full adhesion that still takes about two full weeks of use for AS-5 and other pastes to see a full break in.
 
You can re apply it if you want, AS5 is over rated though, so you may not see a big difference. There are better thermal compounds such at MX-2 out now
 
Odd how up until MX-2 came out, *everyone* praised AS-5 until they were blue in the face. Now, it's 'yeah, that's OK stuff'.

Not a knock, just funny how stuff works...

Anyway, AS-5, FTW (still)!
 
Liquid Pro was the one looked at for a period of time. But that works with an epoxy base there for a one time application. With AS-5 you can clean that off easily enough with some rubbing or denatured alcohol. The important thing is to use one that works.
 
AS5 alone doesn't make much of a difference, I remember MaximumPC running a test with different thermal compounds, and AS5 was only 1-2C cooler at idle then stock, and about 2-4C cooler under load.
 
ok. so should i reapply correctly or not? I did let it alternate, during the day my pc is off, when i come from school i turn it back on, so i did the break in correctly.

x2 - MX-2 was the right choice here.. I picked both up, MX-2 and AS5, AS5'd my wife's computer (parts are comparable, CPU/Cooler are identical to mine) and her's runs slightly warmer (1-3 degress higher). I'll be MX-2'ing hers next :D

If you're not comfortable with your current temps, give it a shot.. the only thing you've got to lose (if done properly) is some extra paste..

It's not always the paste used but how it is applied. One blog seen some time back on how to see AS-5 applied was to stir the small bead down as it is being applied from the tube in order to see the line of silver particles stirred in with the grey paste. That sees the breakin faster with the application. The adequate amount is seen on the photo of one AMD model in the photo here.

 
When I applied mine, I put a small spot like above on and then used a plastic bag as a sort of glove to spread a consistent and thin layer over the whole chip. Seemed to work fine. I used AS5.
 
That's all you do is see a super thin layer spread across the surface. One blog on applying AS-5 advised taking that amount there but stirring it up as you were squeezing out of the tube to a circle about the size of a raisin. That mixes the silver sontent more evenly with the grey base.

From there you simply pressed the hsf down inplace or manually spread it like you do there to see it spread outward across the surface. The merhod reportedly sees the actual heat conduction begin sooner.
