91w tec

[Phantom2024]

can a sever heatsink with a fan cool a 91w tec?

what heatsink? I don't want to answer you wrong but from my experiance with 226w tecs so far, I would never air cool a tec above 50w and even then I would be scared to.

I guess he meant server heatsink?

Probably but I doubt you could go sub zero.

I'm planning to try it with an Koolance RM1-HX Radiator (http://www.koolance.com/shop/product_info.php?cPath=38_77&products_id=206) (100x100x281mm3, 80mm fan). Don't know if it would cut it passive, but forced air should be OK. if you pumped enough water through it you might stay close enough to ambient to go sub zero.

The aluminium heat spreader/heatsink/waterblock on my ram gets quite hot running passive. 1066MHz, 2.5V running Memtest gave 45C at the top of the pipe passive but on 700l/m of MCT-5 the liquid temperature didn't go over 30C

With 1000l/h @ 1.5m head pumping DI water through that RM1-HX and a VAG radiator (400x600x40mm3) mounted in a chimney breast I'd expect the RM1-HX to stay under 50C (assuming T(amb)=25) with heat loads up to maybe 1kW.

I'm going to see how many ~50W TECs I can strap to it before I need fans. Six should allow enough headroom for 400W at full load
