Instruction

Go to Step 10 for the P4 on how to spread the AS5 on the P4. Well, it says you have to just put a "dab" in the center. Well, I put AS5 all over the processor and some more on the heatsink. Could this be the reason why my temp are high in the 50 on stock Front bus? Couldnt this be "better" for the cooling if more AS were applied?

Im not sure if i F myself over or not
 
Just follow the instructions and you'll be set. Don't over paste your cpu and heatsink.
 
I've experimented with different amounts and different ways to spread... the dab and squish method is the best way to go.
 
Well if you're using an empty coke can as a heatsink I'd say your temps are really damn good. We only know half the equation, which is you put too much AS-5 on, whats your heatsink?
 
yea you shouldnt put it on both the heatsink and cpu.
on my p4 i just spread a thin layer on the heatspreader, only recently has the AS website said to do the dab and squish method.
 
AS says you shouldn't tint the bottom of the heatsink if you are using AS5 since it is pretty thick...
 
I personally don't believe the dab and squish method is best UNLESS the IHS is flat. Many MANY p4's i've seen all have raised edges, and if you dabbed and squished you'd have quite a bit of TIM right in the middle, NOT spread out. If both surfaces are flat, i agree that dab and squish is the best method, however the world ain't perfect.
 
Well for AMD processors, I put it on the center piece. And spread it like a thin layer of butter over bread.
 
holy moly! I never knew that putting TO MUCH AS5 would cause such a problem

Can I use nail polish remover to remove the AS5 without damaging the processor?
 
Yes sir.. as a matter of a fact I put too much compound once and my system started crashing like hell.. opened it up.. cleaned it a bit, and then the system was working perfect.. as for cleaning it off.. i'm not sure, i used my finger to clean it off, and i got it all off.. took a while.. but i got it all off... like i said the system worked fine after i cleaned it off..
 
I just use rubbing alcholol when removing arcitc silver. Works like a charm, and dries fast too.

No no no...

Here is a quote off of Arctic Silver's site...

"Do not use nail polish remover as it contains fragrance oils and other contaminants."

The concave heatspreader is typical and one of the reasons the dab in the middle method works so well. Heatspreader is a bit of a misnomer, as the vast majority of the heat goes straight up from the core to the heatsink. Thermal compound on the corners of the heatspreader only serves to space the heatsink further from the core, which leads to more thermal resistance and higher CPU temps.

If you used the squish method and the edges/corners are the only things really touching the heatsink wouldn't the paste be abnormally, and perhaps TOO thick in the center? I've had some pretty bad IHS's, so maybe that's just me
 
The whole point of thermal transfer material, be it a thermal pad or thermal paste, is to eliminate the small air pockets in between the IHS and the heatsink. Metal contacting with metal transfers heat the best, the thermal interface is less effective, and the air is far less than even that. So covering the whole bottom of the heatsink and the IHS will greatly reduce heat transfer since there is no metal to metal contact. Ideally, if both surfaces were absolutely perfect, no thermal interface material would be required, but since this is not the case, Arctic Silver is used. Basically, you want as much metal to metal contact as possible, and is few microscopic valleys as possible, and these are what the AS5 fills.
 
Thanks for all the helps guys. Im going to do the whole thing over again once I get home from school. I'll move on to the 4 ghz range :D
 
Ok, I finally got home and remove all of the AS5 off. I then reapplied it following the artic silver instruction on the website. My temperature is still the same around 50 C. What could I have done wrong?:(
 
Most motherboards report the wrong temperature, what are you using to measure the temp readings? Make sure you get fairly accurate readings before assuming the worst.
 
Im use the BIOS and I also use the Motherboard Monitor 5 Which I think it use the same reading as the BIO. On extensive games , my temps goes up to 58 C :(
 
well, IC-7s are supposedly reading temps about 3-5 degrees too high, but those temps are still a bit high for my liking. Make sure u cleaned your cpu and hsf with isoproponol or somekind of pure alcohol and clean all the ridges in the hsf. Make sure u don't leave fingerprints and oils or accidently get other material on the hsf, AS5 or cpu's heatspreader when applying. After cleaning thoroughly use just a 1/2 BB or the size of a grain of rice of AS5. Mount your hsf and squish down and turn it back and forth slightly left and right to rid yourself of airbubbles and get full contact. The AS5 should spread to a circle with a diameter roughly the width of the cpu (a bit smaller). Perhaps a better hsf like the Zalman would help, but if you're not oc even the new stock fans on the P4 3.0s seem pretty good and redesigned.

Good luck with the temps.

Oh what are the rpms on the hsf fan of yours by the way? Are u using a fan controller of any sort?
 
OMG! I can picture it in my mind. u had a toothpaste toob and just went crazy on it CPU! poor thing :( You should have taken a pic and send it to AS5's website so they can put it up as a NO NO.
 
That room temp could play a factor i believe, like if u were living in Presscott Arizona and it was 135 degrees temps aren't going to be low. Good airflow in your case could help, but the rpms on the hsf seem pretty low. Don't know if that's true, anyone else?

My setup uses AS5 and ZalmanAlCu hsf @ full 2600rpm w/ 2 rear coolermaster fans, one chasis fan and 2 front case fans. cpu temps range from 27 lowest and usually 33 idle to 42 full load or so @ 3.5 overclock with 1.55v (could push a bit more but don't want to cause the voltage fluctuates a bit). This is not accounting for the fact that ASUS boards probably under report the temps, but as long as you're under that 60 mark and around 50 full load it seems ok.

Man, where are you, Alaska? It's been 80 in my room the past several days. :(
 
It's quite simple really, you don't even need to spread out the AS5. Put a nice sized dab in the middle and just let the heatsink and clip pressure do the spreading for you. More so than never, the pressure from the clip will force the AS5 to spread out in a thin circular pattern.
 
Air conditioning or open windows with room fans help keep a cool and happy computer.;)

Can't push this sucker over 240FSB I don't think though so eh, maybe Alaska wouldn't be too bad. Free vapochill, just connect a garden hose from outside your igloo directly to your cpu. :D

Well DavMx, I suggest going to your local Fry's and picking up a ZalmanAlCu. They're quiet and they work very well. Will run ya back 30 bucks or so, but if you're worried about temps and wanna overclock then I say it's a good investment.

Oh, and diredesire, I'd gladly trade u my mushkin for your xms BH-5 and a very big thank you very much :D.

Wow. I think I've exceeded the smiley limit for today.
 
well, The IDLE have gotten better. 46 C. 4 degree less then the first time. But it got worse on full load at 58 C. Maybe I should wait a couple of days for the AS5 to break in?:(

When you pay about 45$ and 7$ for the fan. You kinda expect it to perform pretty well, or its just probably me.
