Pre-applied Thermal Paste

post #1 of 11
Thread Starter 
I was mock fitting my H80i, and the plastic bit that covers the contact plate under the pump fell off. Finger print in the thermal paste.


My first instinct is to clean that crap off and reapply. However, this is my first watercooler, and I'd like some opinions. Should I clean it and reapply. And if so what paste is good to use on water coolers. I've always used arctic silver in the past, but never on a waterblock. Also, paste on the cooler or on the CPU? And whats the preferred method of application, I've always gone with the spiral, but is there a better way?

Just hook it up as is. The paste that the H80i is actually very good stuff.

I figured it was, was really only concerned that the oil from my hand would cause problems, you can see oily fingerprint even off to the side of the paste on the copper.

I have always been told your finger grease Can have a negative side effects...but since it will spread out with that much TIM, i'm sure the Temps won't differ by more then 1-3C tops. smile.gif

there is no problem with the block or the thermalpaste even though youve touched it
itll take a bit of cleaning for your fingers though redface.gif

just dont get that stuff on your shirt, it hurts frown.gif

no you dont have to reapply it, wasting thermal paste is a bad idea, its so expensive frown.gif

many ways of applying thermal paste, to each his own,

some people apply a load and spread it with a glove
some people spiral it
some people make a line in the middle (i do this)
some people go ape**** and use the whole tube of paste on one mounting

all of the above is fine, thermalpaste acts as a heat conductor by levelling the curvature on ur cpu to make full contact with the base of your block, as long as you have enough paste to contact the entire base of the block its fine

you're basically asking if theres different ways of spreading peanut butter on bread tongue.gif

just remember the more thermalpaste you put on the more **** you gotta clean up afterwards redface.gif

No,its not for that at all,its for filling the microscopic voids and to insure maximum thermal contact. Less is very much more with TIM,you want the minimal amount possible for good contact,not as you put it 'go ape with the whole tube'

The pea method is considered best,larger dies would benefit from a cross or line method

Whatever method - I myself put a dab on and scrapped with a card after. Your trying to fill in micro pits that you cannot see with the human eye.

The best heat dissipation is metal to metal not the paste itself. Hence lapping etc .

If wrong please let me know thumb.gif

I have another question regarding the H80i, a different aspect. The pump connections :


The one on the left is a 3 pin fan connector, does it matter if it goes on a chassis fan, or a cpu fan header?

And the SATA power connector, I assume that just plugs into a spare SATA plug from the PSU?
