I have an ASUS B85M-G motherboard, and when i touch the chipset heat-sink(after about 20 min) it gets really hot, too hot to touch after about 4 seconds(i know that it is safe). but should i concentrate the airflow over that to cool it down. also a while back, i overclocked my g3258 on the motherboard, and it was stable for about 2 hours(on 4.2GHz) until i decided to turn it off, since i didn't think it would crash. anyway the next day i have it running and i do some bench marks(the unigen heaven) and with in about 10 minutes the GPU was at 92°C, and then let it cool down, and turned off the whole computer. and after about 30mins, turned it back on and i then played minecraft(a real easy game to run), about 10mins in it crashed(the graphics card), the screen was flashing black and white. so i force restarded it, and then went to play it again, and it crashed again, similar thing happened. then once restarting it again i showed someone else(to see what they thought of it) the temperatures of the gpu on a light load. he suggested that there was some dust in the heat sink. so i pulled it out (this time i did a normal shutdown) and saw that there was no dust and then put it back in, and the computer was dead, but i found it was the motherboard also my graphics card was a gtx 260, which was working fine and not getting that hot in another computer, and did not break on close inpection, we found that a chip, which looked like a vrm for the pci-e slot, had blown or smoked. So my questions are: 1. is the temperatures on the heat sink fine and also should i direct more airflow over it 2. did that dead vrm near the pci-e slot cause the whole pc to break and not turn on, or was there something else as well that cased it to break. 3. was my gpu not up to the task of been with an overclockable cpu, and drawed too much current, which caused the vrm to smoke. 4. would it be safe to overclock on the same motherboard (i got a new one under warrenty(somehow)). And i also have a different gpu now that draws less power/ 5.if it should be ok to overclock, would it help if i put a heatsink on the vrm's to cool them down disclamer: i know this isn't a 'z' motherboard, but asus think it is fine to overclock on the non-z motherboards. sorry this was a bit of a long post Thanks in Advanced
