I am hoping some experts will give me some guidance on how to address overheating issue.
My systems shuts down all of a sudden (like plug was pulled out) without a warnining. I have downloaded PC wizard to check temperature. CPY temp idle is around 80c !! Under load it reaches 90 and that is when it shuts down.
I am not sure why it is that hot since all fans seem to be working and it was working ok up till a week ago.
CPU: Q6600 (not overclocked)
OS: Win XP Pro 32bit / SP3
MB: Asus Rampage Formula
Graphic Card: ATI 4800
Memory: 4 Gig DDR2
Any help with this is HIGHLY appreciated as I use my PC for work.
Any chance you've moved the PC recently? Sometimes moving it can force a CPU cooler to come loose. With the system powered down, see if you can wiggle it. Do so gently though. If it's loose, you should be able to tell with little pressure applied. While you're checking it, see how dusty it is.
Have you checked temps with the case open, or only while closed? And if open, any chance you can aim a small house fan at it and see if temps change and by how much? If they drop, you have a ventilation issue - the case simply isn't getting enough airflow. Check for dust again, this time on the intake fan(s) and/or along the air intake vents.
If you find a lot of dust, a can or two of compressed air and a soft-bristled brush can go a long way. Just be sure to clean the case outside.
try to move the CPU fan/heatsink with your hand, if it moves a bit that means it might have been unhooked or something and you need to screw the 4 plastic screws around the heatsink until it stops moving.
if it isnt moving in the first place try what the other people said ^^
It's still a bit on the warm side, but acceptable. I'm curious if those temps are with the case still wide-open, or closed, as the final evaluation should be made while the PC is in it's preferred position, whether closed or open-case. If the temps go back up, you may want to consider completely removing and separating the heatsink/fan, cleaning them, and reinstalling with new thermal paste, as has been suggested. If that still doesn't bring the temps down enough, you might want to consider more efficient aftermarket cooling solutions and/or increasing the total airflow of the entire case.
CPU fan set to high (90%)
I have not applied any thermal since building PC (a year ago) I have ordered Arctic Silver5. I figured I will start by applying a fresh coast of paste and see if temps go down. 50 on idle is a bit high judgying from others cpu temps. The comp does shut off if I am rendering HD video or playing an intense game.
If thermal paste is not enough, could you guys recommend a CPU cooling fan that is reasonablly priced and more imporrtantly "NooB friendly" (ie. easy install)
I really appreciate your detailed response and I will order one of those coolers.
Going back to the heat issue, I have noticed in PCwizard that the processor voltage is 1.29 volts. Is this too high? Could it be the cause of the high temp?? I have 4 fans inside the case so the high temps at idle seem very odd ..
That voltage is right in the middle of it's spec range, which is between 0.85 and 1.5 volts. It's fine.
Is there any chance Intel SpeedStep isn't enabled within the BIOS? SpeedStep is a clock and voltage management function that basically slows down the CPU speed and reduces voltage while the CPU is idle in order to save power. It also keeps it cooler while idle.
Regarding your cooler purchase, there's no need to rush into that based on one person's opinion. Especially someone who doesn't live in the same country and has no experience buying from those merchants
About the system fans. Would I be correct in guessing 2 are intake and 2 are exhaust, and that they're all identical? If this is true, then you may actually want to change it to 3 intake and 1 exhaust. With the PSU and possibly the video card also venting exhaust air, a 2 intake / 2 exhaust config actually means the system has negative internal pressure, trying to vent more air than it's taking in, so it's sucking in extra air through cracks and vents. But a 3 intake / 1 exhaust would change it to equal or positive pressure, meaning it's pushing air out through vents and cracks, which is a the better path. Especially if the intake fans have dust filters. That way no dust sneaks in through the cracks and vents. Basically, it keeps the internals cooler and cleaner.
