paralolegram Posted April 2, 2012 Share Posted April 2, 2012 After upgrading my Psu to 750 Watts and video card from Gts 250 to Gtx 560 Ti, I was checking temps of my video card and cpu. Turn out my video card temp is fine but my CPU temp seemed high to me. I have a Intel E8400 3.0 Ghz CPU, During idling it sits at around 50-60 degrees C, while gaming it jumps to anywhere from 80-95. Is this normal? I have one fan on the rear of my comp on exhaust at this moment. I am also using the heatsink/fan my CPU came with. Quote Link to comment Share on other sites More sharing options...
greenknight Posted April 2, 2012 Share Posted April 2, 2012 With a little search for the specs of that CPU, I found that the maximum temp is supposed to be 72.4 C. So no, that's way too hot. Is the heatsink clamped down properly? Quote Link to comment Share on other sites More sharing options...
Administrator Tarun Posted April 2, 2012 Administrator Share Posted April 2, 2012 You may want to verify your temps using OpenHardwareMonitor and you may also want to try CoreTemp. Quote Link to comment Share on other sites More sharing options...
Eldmannen Posted April 2, 2012 Share Posted April 2, 2012 That Open Hardware Monitor seems cool, I'll try it, thanks! :) Quote Link to comment Share on other sites More sharing options...
paralolegram Posted April 2, 2012 Author Share Posted April 2, 2012 Theres some dust caked ontop of the cpu fan, i will clean that and see if it gets better. Open Hardwaremonitor gives me the same temp ranges. List of stuff i will try x.x 1.Clean CPU Fan 2. Get a side 80mm fan 3. get a new heatsink/fan 4. Get a new case Quote Link to comment Share on other sites More sharing options...
greenknight Posted April 3, 2012 Share Posted April 3, 2012 So, not an April Fools joke? I had my doubts - 95 C is really. really hot. Yes, cleaning the CPU fan and heatsink is the first thing you should do - may help a lot. Make sure you have unrestricted airflow around your case vents, and that they're not sucking in hot air from some other heat source. You seem to have a good handle on what it takes to fix this. Good luck, hopefully you won't have to go all the way to step #4. :rolleyes: Quote Link to comment Share on other sites More sharing options...
James_A Posted April 4, 2012 Share Posted April 4, 2012 +1 Some CPUs won't actually survive temperatures in excess of 95 C. An E8400 Core 2 Duo is listed as Max TDP of 65W so cooling should not be a big problem, even with the stock cooler, unless (as you have discovered) the fins are blocked-up with dust. Here in the UK, Custom PC carried out some comprehensive case reviews and showed that the case (and its airflow) makes a BIG difference to the temperatures inside. Not surprisingly, expensive cases did better than cheap ones, but you can approach the best of both worlds with something like an Antec 100. Good airflow is usually achieved with intake on the front (with a second intake fan if needed) and a fan exhausting at the rear, or on top, with the CPU cooler set to blow out in the same direction. .

greenknight Posted April 5, 2012 Share Posted April 5, 2012 My old Duron CPU would crash when it reached 95 C - and it had a max temp of 90 C, they were some of the hottest-running units ever made. Modern CPUs, instead of just crashing, reduce power to cool down. That means something has to be badly out of whack to get one that hot. That's why I wondered if the heat sink was loose - though it could just be really clogged with dust. Wouldn't have thought it could be that dirty if you recently worked on it.

Eldmannen Posted April 5, 2012 Share Posted April 5, 2012 I just tried above mentioned Open Hardware Monitor. It works great! Quote Link to comment Share on other sites More sharing options...
paralolegram Posted April 6, 2012 Author Share Posted April 6, 2012 After clearing the dust Idle temp is around 45 now thanks everyone! Quote Link to comment Share on other sites More sharing options...
greenknight Posted April 6, 2012 Share Posted April 6, 2012 You're welcome. Guess it was pretty dirty. Still would be a good idea to add an intake fan, an idle temp below 40 C would be preferable. 80 mm fans are cheap, so why not add one?. For that matter, a better cooler wouldn't be too expensive - a lot more trouble, though, I'd try another case fan first. And remember to blow the dust out once in a while.
