I have some cheap heatsinks on the mosfet and a 120mm fan right on top of them but they still get pretty warm. No fan on them its dangerously hot as well for the vrm's.
Ive undervolted it to 1.3v from 1.37v at stock clocks to just lighten the load on the board, as I let it crunch 24/7 for this weeks SuperComputer challenge.
I had the same MB and PSU and came to the conclusion it was the MB. I put the 1055t into a Gigabyte MB and it would boot to Windows no problem. I have even gotten it to boot to 3500Mhz at stock voltages, although I had a different issue. I know Biostar stated that MB supports the chip, but I do not think it does since I could put my 435 Triple core in and it would boot just fine. Right now I am testing two Gigabyte MB's to see if both support it so I can decide which one to keep. Since this is for a WHS box, I will go with the cheaper of the two.

Anyone with a Gigabyte MB that can tell me what I have to disable to get it to stop downclocking? I disabled C1E, Core Performance and QNQ, what am I missing? I actually got it to go into Windows and start folding with 250 x14 (1055T) at just 1.39v, but CPUID only shows 1000Mhz (250 x 4). HT was at 2500 by the way. I think these chips have some potential, but trying to figure out these bios' is a PITA.
