Everytime I start my computer my MB temp sensor says 41c (my comuter was just running prime for 2 hours) cpu-z will tell me my cores are at idle temps around 27-30c. I am using the stock 3000+ HSF on athlon II 630 (which came with an awful HSF). So should I just ignore the MB sensor and as it usualy reads 10-20 degrees higher then my processor thermal sensors?
