Re: How much heat sink?
If you're only drawing 34 amps and still blowing 60 amp SSRs with added cooling it sounds to me like you still have an electrical problem along with you're cooling.
How big is the is processor heat sink and fan you are using? If it is one of those that fits on the bios chip or something that is far too small. For a computer heat sink and fan you need one for probably a pentium 4 chip. The extra one I have here I have in mind is about 3" around and 2" tall with a fan on top and one on the bottom of the heat sink. But I also have some heat sinks in storage somewhere that where used for radio power amplifiers, I might just bolt one of those on there since they are pretty big.
For DC power for a cooling fan you should be able to go up to Radio Shack and get a small 120vac-12vdc or 5vdc transformer like what you find in the back of radio's and stuff, you should be able to wire that in no problem. Hell, cheaper yet you could take the power supply out of the computer you got the heat sink out of and just wire that to the AC, then connect you're fan to the original plugs.
