Most of them will run anywhere from 5 to 12 volts. The lower voltage just slows the fan.

I would have thought they were 110V being in a comp.. thanks for the info

Thermogard? computer fans? Get real.

I simply cut the top off my Turbostart, cleaned out the plates (easy once the top is off) then tapped the posts (easy once the top is off) and installed cables. Then siliconed the top back on to the case.

Didn’t even put a scratch in the case or top. It’s beautiful. As beautiful as the day I bought it 9 years ago. You cannot tell the top was ever removed.

He is talking about keeping a lithium ion battery temp down. They are very temp sensitive. They need some airflow for cooling. A 120mm ( about 4 3/4") fan moves 44 C.F.M. Best Buy has them for $10 but as I said, sometimes you can find them for free (maybe not as good though). Here is a link 120mm fan

They are 12VDC, the simpler ones are 2 wire, a positive and a negative. The newer ones are 4 wire, with a sense and a control (rpm). Here is a cool link that talks about them: 4 wire fan explanation

I would just get a 2 wire, the older ones for ease of install. I would also go with some kind of heat sink on it, surround it in some aluminum would work I think and have a fan in there it still gets too hot.

I salvaged a small computer fan for an amplifier I added to another car. That and the aluminum heat sink...good ideas!

Nice work Dave. I once found about 10 old computers being thrown out, near Christmas. I took all those old heat sinks and zip tied them to my exhaust pipe from the heater (natural gas) in the basement. I'll say it warmed up the area a couple of degrees just by using those heat sinks!
