E8500 running at 90C

[Salil]

Hello,
I have E8500 which after bootup is at around 60C and when I run games etc. it is at 90C. A couple of times my CPU has shutdown, I believe because of overheating. I have used a variety of utilities (speedfan, real temp, bios) to check the temperature and they all say the same. I cleaned the insides of my desktop and still the temperature remains high. All my CPU and chasis fans are working. I have this desktop for about 1.5 years and it is only now I am noticing this problem. I was wondering if it is because of me using the stock heatsink and fan that came with intel. My motherboard is pretty hot at 50 C too. Please give me some recommendations

Unmount the heatsink, reapply thermal paste and mount. Personally, I would get an aftermarket cooler. Something like the Cooler Master 212 Hyper Plus which has a fantastic price-to-performance ratio.

sounds like that fan on the stock hs is on its way out. get a quality unit if you want to OC.

I removed the existing thermal paste and I reapplied a new one. The temperature fell down to 48 C. However, when I went into the BIOS to set my cpu and chasis fan speed to max, I noticed the temperature had shot up to 88C. After I went into vista it fell down again to 48 C. My fan speed at max is a constant of 1406 rpm. When I read most posts I notice that fan speeds are at 5000 rpm max. I am wondering if something is wrong with my fan?

what app is telling you it's 48*c ?

 

[Salil]

speed fan and asus utility ai suite.

Try Hardware Monitor or CPU temp and let us know the core temps

 

[Salil]

I used real temp and it is telling me that same thing 48C when idle.

Thanks a lot all of you. I did try removing the heatsink. removing all the thermal paste and putting back the heatsink. That didn't help. I am leaning towards the fact that the heatsink may not have been inserted properly as shown in the page http://www.supremelaw.org/systems/heatsinks/warning.htm. I will try inserting the heatsink again. However, I am worried that applying too much pressure might crack the mother board. Also my GPU ATI Radeon HD4870X2 is running very hot. Don't know the exact temperatures but it seems to be very hot to touch. Much hotter than my CPU. Don't know if that is affecting the temperature.

Salil, just find a Cooler Master Hyper 212+ on sale (now and then for $25) and buy it. Seriously. The time you will have spent posting about this in forums, researching online and endlessly reseating it and putting on new TIM... if you charged yourself minimum wage for that time you would have lost money over just buying the new heatsink.

The 212+ should be an order of magnitude better than the stock E8500 heatsink, plus it is compatible with newer sockets so even if you upgrade CPU/motherboard you will be able to reuse it (until another new socket comes out).

Zap, I do have to get to the bottom of the issue. I totally agree with you now, that I should go and buy the new cooler master hyper. I was wondering how I could get it as fast as possible. are there any hardware stores that sell them? Since shipping usually takes time unless you want to spend more money in express mail.

I installed Cooler Master 212 Hyper plus and threw away the stock intel cooler. My CPU temperature fell to 25 C. However, my mother board temperature is still 52C even with the case open. It might be because of the radeon HD 4870x2 running very close to the south bridge. I am a bit disappointed with the cooler master the thing is humongous. The cooler master 212 was so huge that I had to remove a 250 mm fan from XCLIO A380 case in order to close the case. The case wouldn't close because of the copper welds at the end of the heat pipes. I wish they had shown the sense to file it away.

if you think the cooler master is humongous...

a cpu heat sink isn't going to do anything for mobo temps. mobo temps will run what they run basically regardless of other components. my cpu runs barely above ambient, my video card doesn't even have a fan, and my motherboard still runs 50+ degrees. it's not an issue.

I agree with the Cooler Master Hyper 212. I have a E7200 under one, and the idle temps are 37/40 and load is 43/44.

After I installed the Hyper 212....I overclocked from 2.53 to 3.8 and guess what ?

The idle temps is 37/40 and load is 43/44. I then pushed it to 4.0GHz and the idle temps were 39/41 and load is 43/45.

I have a push/pull fan setup. So yea, excellent cooler. I also plan on using it on Ashley in sig.

That is WAY too hot. You need to be under 71.5C for a guaranteed 3+ years of operation.

60C idle is extremely high. Take the advice in this thread and re-do your cooling.

It's probably due to a faulty HSF mount.

I've had the E6550 idling at 65C for about a year and then it jumped to 80C. Found out that 2 pins of the HSF were released. Re-applied the thermal paste and it was all good again. Idling about 40C now.
