+1 on the Arctic Silver adhesive
Also check out the EnzoTech mos-c1 heat sinks they look like they may be perfect for opamp use.

Thanks for the heatsink help, guys.

If I'm looking at heatsink dimensions (farnell has a pdf with a wireframe pic), how would you choose the size in relation to the target IC socket? Should it match exactly or be a fraction bigger in order to definitely fit?

Is there any ongoing group buys of the O2 kit to Europe(Norway)? I saw Jokener, but doesn't look that hi respond anymore.

Hey guys take a look at my custom machined stainless steel front panel if you haven't seen it already. I think it turned out pretty good myself but I may be a little biased.

Also I've got an extra fully made O2 up for auction on eBay if anyone's interested.

Hi everlong,

I have around 100+ part kits in stock for the O2, unfortunately I am on vacation till begin of May. So can only take your order once back. I posted in the GB section with more details. The link to my site is in my footer.

Hi, first time poster and long time lurker here. A bit late on heat sink discussion but I used Zalman VGA ram heat sinks in my last O2 build. The heat sinks fit very tight and barely get away without touching the capacitors, mosfet, and battery.

Holy cow, that looks heavy... and very nice. I like the look of SS over aluminum any day.

That heatsink looks great! Once the board is safely in the case I wouldn't think anything will move around enough to cause any unwanted contact (unless perhaps the O2 suffers a long drop onto a hard surface).

Nice heatsinking job with the zalmans - is it really worth the trouble though to heatsink the opamps?
