Two different compound

Gardinen · Dec 2, 2003, 02:44 AM

I'm getting a heatsink which have preapplied thermal compuond. Which means that the CPU doesn't have anything on it. Can I use a white thermal grease which I have left over to use on the processor??
This would mean that I'm, or at least a big chance, using different sets of thermal compund. Although both white grease.
Would this do anything to the heat??

.....could.... to much.... i'd scrape of (with something that can't scratch the metal... perferbably nothing near the hardness of a diamond

) such as plastic would work..... (soft plastic)...... apply your own thermal grease.... i've heard and seen some bad stuff happen when you apply your own thermal paste.... along with leaveing that preapplied stuff on..... makes not only a huge mess.... but the temps seem to go up.... (

Yeah i agree wiht judas. Either scrape of the factory stuff and put on you own or leave it alone and just run the thermal pad that comes with it. By putting more on it you may do more harm than good. Your best bet to me would be to get rid of the factory gunk and put on some yourself nice and thin>

don't trust that factory crap..... it's the last thing you will want..... the worst is knowing that it's not probably that great... and just sticking it in a machine anyways.... 1 of 2 things will happen.... 1 being that your cpu a: quickly dies.... b: dies fairly soon... or 2: you get nervous and take the cpu out and clean it up.... but you'll have more work as the cpu will now be somewhat covered but this crap.... i've seen someone do this.... boy were they upset... specially after i told him about it... then simply said "i told you so"

There isn't a thermal pad applied on the heatsink. It's preapplied cheramique compound. And it's said to be a quite thick layer of it.
The thing is...do I need to apply some extra cheramique compound on the processor as well, or could I just put on the heatsink with the goop and be happy?

And again: It's NOT a thermal pad on the heatsink, it's preapplied cheramique compound.

I still would not trust it. To me it is not a thick layer you want it is a nice thin even layer for the best transaction of heat away from the CPU to the heatsink. If there is a thick layer of it it will not be effecient.

i'd still remove it as toddsmack said... sorry....i never seen or heard of anything what you mentioned....

peterosesbookie · Dec 3, 2003, 02:55 PM

I'd remove it all and apply your own or Artic Silver 5

the first time i got a stock p4 h/s I scrapped off the pad and lowered my temp by 10c!
I put some white thermal greese on it that time.

Then I bought a Coolermaster lite H/s fan turbine thing.
I used it on the processor for a while and then scrapped the silver gunk it had on it off
and applied Artic silver 3. that lowered the temp quite a lot.

I was sure I could get lower temps through, so I removed the heat sink off a compaq
evo to see how much greese they applied to a p4 and noticed that they only used a
very small amount

I spread it thinly but i spread it right to the edge of the pro , making
sure that the whole of the processor is covered .

what they do is just use a round patch in the middle leaving the edges without any
greese on it, I have tried this , believe me this is cooler but make sure you use enough
a cpu would overheat very quickly if you got it wrong.
I have very low cpu temps now, I feel a bit of a geek but ive lowered my cpu temps!!!!

the factory stuff is like wax... it's the worst themal interface material but it's cheap and stays put..

Well the Arctic Silver 5 is very nice to work with. It's just like hot bubble gum. I used a razor blade and had now problems getting a nice layer.
I've got around 45 degrees fullload with the SmartFan II at 3800 rpm

If you want better temps......throw on a Tornado fan and hook it up to a rheostat.....a bit more noise......but you can control it and turn it up on those hot days

Gardinen · Dec 17, 2003, 06:41 AM

Ok Roadee. By the way, what's your temps on the CPU + case? And how fast do you have your tornado fan runnin?

**Roadee** · Dec 17, 2003, 05:58 PM

Using the "winbond" hardware monitor that comes with the NF7-S, and with a room temperature of 70 F.......just doing normal things, surfing, office xp, burning cd's........

Fan speed: 3800 rpm
CPU Temp: 38c
Sys Temp: 25c

Fan speed: 5800 rpm
CPU Temp: 34c
Sys Temp: 23c

And this is with a 2500+ Barton overclocked to 3200+ at stock voltages and stable as hell. When I am benchmarking or gaming, I crank the fan up to 5800 and never hit 40c. This lower level of heat will allow my CPU to live a pretty much normal life span, even though it is overclocked to a 3200+.
