Those seem to run hot. A small heatsink can't hurt... I usually use Ceramique, with a small dab of AS adhesive in two of the corners, and place a bit of weight (not too much) on top while it cures.

A little airflow in the case doesn't hurt, either. I use a Nexus WaveAir, with the PCI bracket modified to attach to the empty slot between the CPU card and the first Zorro slot. Undervolted 40mm fans come in handy, too.

Personally, I would stay away from thermal pads. If you want to attach it easily and permanently, this or this is the way to go IMHO. But I still prefer using adhesive only in a few corners, and covering the rest with regular thermal compound.

Hi Barney,

Quote from: barney;521886
Ok, thanks for the info.  Now with this arctic silvers, it states to keep it away from electrical traces.  This cpu on this particular accelerator is quite small (about the size of a quarter.  I know how cpu paste tends to squeeze out and get all over the place.  Is this going to be the case with this stuff?  Does this stuff tend to creep after it has been applied?  Also, the space between the CPU and my DF1: floppy drive is approx 1.5".  Do you know of a place to purchase good heat discipating, think heatsinks that will fit between this space?  Thanks.  Also, between these two artic silvers you listed, which do you prefer,the Arctic adhesive or the Arctic Ceramic Adhesive?

This is what I do:

1. Clean both surfaces (using ArtiClean, or just regular ISO is OK)

2. "Tint" the heatsink surface with a small dab of Ceramique (described in the online docs)

3. Place a very small dab of Ceramique on the processor surface

4. Place two tiny dabs of the ceramic adhesive in two corners (pre-mixing is not really necessary, just a small bit from each tube on top of each other)

5. Fit the heatsink, applying a small amount of pressure, and some twisting to help work out any trapped air, spread the compounds evenly, etc

6. Place a bit of weight, perhaps something like a small glass with a medium-size paperback book on top, and let set for at least an hour

It won't ooze much if you take your time and don't get too crazy with the compound. Cotton swabs soaked in ISO easily clean anything that might seep out.
 
All that said, I agree that doing all this (while it works well) might be a bit excessive. For me it's simply a hobby and fun, plus I already have all the compounds/thermal glues/heatsinks/etc laying around. Thermal tape and a small fan will also work good enough, if you'd rather take an less time-consuming route.
