Hello! I recently built a budget gaming rig from my friends' old components. My problem is that the AMD Phenom II X6 processor is at a constant 67-ish degrees Celsius in idle. The system is very slow due to the CPU going back and forth between 800Mhz and the stock 2.8Ghz. I am using a Xigmatek HDT-D1264 cooler with Arctic Silver 5 thermal compound, which worked very well in my old Phenom II X4 840 System. If anyone could enlighten me about the problem I would be forever grateful.

Thanks in advance!

specs:
AMD Phenom II X6 1055T
MSI 970A-G45 socket AM3+ motherboard
8Gb Team Elite+ DDR3 1600 RAM
Sapphire Radeon HD R9 280X Vapor-X Tri-X
SSD Samsung 840 120Gb
EVGA SuperNova G2 850W PSU
case: Cooler Master HAF 912 Advanced

Thank you for your response! I do not think that the problem lies with the cooler. I have now tried the 1055T in my older MSI AM3 motherboard but with the stock cooler instead of the aftermarket one and it's running fine. I also tried my older Phenom II X4 840 in the newer AM3+ motherboard with the Xigmatek cooler and it stays at a frosty 15-20C idle. I recently bought a Cooler Master Hyper 212 EVO though, so I'll install that and update with results when I have time. Another weird thing is that when I try the AM3+ motherboard with an old Gigabyte 7950 windforce and/or 8Gb of Kingston RAM that I got together with the motherboard from a friend, the computer won't post at all. But when I put in my newer Sapphire R9 280X and my Team Elite+ 8Gb RAM it works, only the 1055T gets overheating problems but the X4 840 works fine. And the Kingston RAM and HD7950 works perfectly with my older AM3 motherboard. I am really confused, but the problem seems to lie with the MSI 970A-g45 AM3+ motherboard...
