Re: Ratdude's Main rig V3.5
When I got the Thermaltake water cooler a few months ago it already had paste applied. Spread out all over the bottom. When I do output transistors, I always cover the whole backside of the transistor. I don't think it matters whether it's spread or put in a blob. Just so it covers the whole contact point when mechanically fastened.

We are talking about a temperature difference of 30°C if using a "normal" heatsink.
Not a problem in any way, actually just good because it allows the paste to creep out, the hotter it gets...
What they mean with the "burn in" period is that when that time has passed the paste will have settled and offer maybe 1 or 2°C lower temps than before it had settled completely.

In the normal state, it's a paste and as it heats up it goes liquid and enters those microscopic imperfections in the metal, trapping whatever air atoms (or whatever) are still in the middle. So basically, you no longer have air between both metal surfaces.
You should know but just in case someone stumbles on this post in the future...
Just apply the solder paste the proper way... clean both surfaces with isopropyl alcohol (or regular sanitary alcohol), dry the surfaces, put less than pea sized drop of paste in the center (or a thin line if the die is very big) and press the heatsink on top of that drop.
As you press, the drop flattens and pushes the air between cpu and heatsink out.
Don't put paste and spread it over the whole surface and then apply the heatsink.. if you do that you just trap a bit of air between paste and heatsink.
It doesn't have to cover the whole chip die and overflow, as the paste gets hot and more "liquidy" it spreads by itself under the heatsink.

Re: Ratdude's Main rig V3.5
^ I take it you meant thermal paste not solder paste... I'll edit in a fix if you want.
Noted on not needing to cover. Never knew that... Duh. Noted.
Orderign some AS5 then.
edit: getting it in bulk: http://www.newegg.com/Product/Produc...82E16835100008
Since I'll be redoing a lot over time (when laptops are due for cleaning, V2's CPU's could use a redo as well.). I figure it doesn't expire that quickly so it's probably good to have around.Last edited by ratdude747; 08-14-2013, 10:19 PM.

Re: Ratdude's Main rig V3.5
my main concern with a burn in period is not being able to use the system for 200 Hours... is that the case?

Unfortunately, the RadioShack stuff likes to fade away after some months of use.
Took socket 462 heatsinks off more than once, IIRC, to see it disappeared from the Athlon!
No such bull with Arctic Silver 5.Last edited by RJARRRPCGP; 08-14-2013, 01:24 PM.

I never had good luck with Ceramique. It worked fine for a year, and then the temperatures started increasing. I'd rather not take the heatsink off that often.

Re: Ratdude's Main rig V3.5
Use whatever the OEMs (HP, Dell, eMachines/Acer/Gateway, Lenovo, Toshiba, etc) use because most people run their ten year old PCs and have never reapplied the TIM nor even know what the heck it is LOL...
Alright, maybe I'm kidding, a little bit, maybe not?

Re: Ratdude's Main rig V3.5
I always use AS5, and it seems to do great.
As far as the furmark temps, I once did it to a passive 8500GT with a somewhat small heatsink (Thanks ASUS!). It maxed out at 105*C. You could just about cook eggs on it at that temp.Last edited by c_hegge; 08-13-2013, 12:27 AM.

Re: Ratdude's Main rig V3.5
I don't know, looks like generic paste to me. If it was any good, it would list the specs on it.
The gelid site lists it as 8.5W/mK which isn't anything special.
Look for pastes that have better thermal conductivity, for example the Prolimatech pastes are advertised at 10.2w/mK
http://www.newegg.com/Product/Produc...82E16835242024
But then again, Tuniq TX-4 is recommended by a lot of sites as a good general paste and it's only rated as 6.3w/mK.
It makes a lot of difference how thin the paste is applied and so on...

Re: Ratdude's Main rig V3.5
AS5 is a bit old at this point but still excellent and it seems to have come down in price a tiny bit.
The differences between all of the really good pastes including AS5 are like 1-3C so just find one you like an use itAS5 would be my recommendation that said.

Uh oh...
When I redid the heatsinks, I used this for the GPU die:

I take it that's not good enough... What is suggested to fix this?
