Too thin a layer of AS3?

CheeseBall · 07-06-2003, 12:27 PM

I made my own WB awhile ago (similar to WW), and have had my 1.4ghz Tbird (clocked to 1.5ghz) running load at around 45C. Which I suppose isn't too bad for a tbird but it really should be better.

When I applied AS3 I had the excess from rubbing it in to my WB on a zip lock bag. So thinking I should have as thin a layer as possible, I just dabbed my CPU core (w/ the zip lock bag) to cover it all. Is this too thin a layer? My WB is lapped to 600 grit.

I am going to remount w/ out springs this week so I will re apply then. I'm thinking I'll try a heavier coat.

that's usually what I've done in the past... never had too much success with the razor blade - I allways seemed to put too much with it (in my opinion)

I've had fairly decent results with reasonably flat and smooth heatsinks.

I am curious to hear what other people think in regards to how much paste is enough and how they apply it.

Well, after remounting w/ a thicker layer (thinnest layer I could do w/ the Credit Card method) and no springs my temps have risen. I also now have more torque on the block from the tubing, but the no spring mount should take care of that. My temps now load are 51C. But the layer of AS3 hasn't set up yet, and maybe the air bubbles aren't all out yet. I doubt that will make a 6C change on its own.

Looks like I'll have to: bleed, remount, and fill again. Woohoo.

The zip~lock bag was a good idea. My idea was to use some clear sticky~tape and take an imprint onto the non sticky side and then 'dab it on' to the CPU core. The credit-card/razorblade method sucks IMO, may have been OK when paste was thinner/less~stodgy than it is now :shrug: ...

This is how I apply thermal grease...

- put a small amount of grease on the core itself

- grab any clean plastic bag (a grocery bag is usually handy)

- turn the bag inside out (the inside is usually cleaner than the outside)

- put my index finger in the bag and stretch the bag around my finger so the bag is really tight and is not creased at all

- using said finger I spread the grease over the core (going from the center out to the edge - to avoid getting grease on other parts of the CPU)

- rub whatever grease is left on the bag to the bottom of the water block (or heatsink - do people still use heatsinks???

) right where the core will touch it

- install the water block (twisting the block a little once installed)

Using the above method I have never had any problems.

I use the same bag method.. usually a fresh new sandwich bag, inside out and streched smooth. I am able to get a thinner more even spread this way, and less mess. Credit card/ Razor method = SUxor IMHO.

Plastic Wrap used to keep food preserved in the fridge wrapped around finger.
