I5 2500 CPU Overheats to 95 C rapidly

[Arstik]

may be, but its still does its job very well and does not rotate 100% speed all the time and its still way better than normal heatsink, also its cheap.. PH-TC14PE costs 89euros at finland so u can see my point.

[Slizarus]

The CM 212 Hyper + did the trick and now BIOS reads 50 C and stable, Now I need Win 7 on it still, and I have a Bad DVD, but I'll make a new one at school tomorrow. Thanks for the assistance.

stock fans are never good.

That's not true. Unless you plan to overclock, the stock heatsink is just fine. Mine is cooling the cpu at 27 idle up to 38ish in load.

Also, i think the stock fan doesnt spin faster than 2200 rpm. At least mine doesn't when i set it to full, its a stock i5 2500k heatsink.

Full load from what? lol Your temperatures are beating most custom liquid cooling systems. If you're judging based on a game, that's not your load temp lol

Run a couple of hours on Prime95 and check the temps again.

About an hour on prime95. Im talking cpu temperature not core temperatures, those run at about 60-65 degrees at most :P

Oh, that temperature is obviously false then. Can't have a lower CPU temperature than a Core temperature considering the Cores are what generate the heat lol.. Common sense ftw?

Motherboards are what derive the CPU Temperature. The Cores have their own diodes directly on them so yep, false temperature

I think the sensor picking up the lower (single) temperature is located somewhere on the processor, not that close to the cores, maybe closer to the surface? Anyways, cores run at 33-35 degrees on idle it seems, so thats a more valid reading :P still pretty decent for a stock cooler i believe! I plan to overclock at some point though so obviously ill be going for an aftermarket heatsink!

CPU Temperature is read via the socket. A Temperature read from the IHS(top of the CPU) is called a tCase temperature but Intel does not put tCase diodes on their CPU's and neither does AMD.

The only temperature that's even relevant for an Intel CPU is their Core Temperatures which come directly from diodes placed inbetween the IHS's solder and the cores themselves.

[Medivhe]

Makes sense, i'll keep that in mind. I only switched to intel like a month ago (after not giving a damn about my old 2005 amd temperature :P)

best bang for the buck cooler is cooler master hyper 212 EVO you'll have to look it up on newegg i can't post links yet lol also on youtube can look up "reseatting cpu cooler" lots of vids to show you how to install a cooler.

your temps should't be that high at all and your not overclocking so that ain't causing the temps to be that high either it's the way your reseatting your cooler or there's something else wrong maybe faulty motherboard if you get the hyper 212 EVO and your temps don't drop i'd RMA the motherboard and have newegg send you a new one i'd also pick up another 120mm fan for the hyper 212 EVO so you can run a push/pull to get better temp results.

Indeed, they aren't amazing, but with sandy and Ivy bridge they can even be used while OC'ing a little. I don't think the stock cooler's the problem here.

I just read this post during I'm searching some infos about the 2500k and decided to quickly register to help you.

So, my thoughts is that the temperature value is expressed in degrees Fahrenheit :

95°F equals 35°C, it's ok for an idle CPU

The title actually says 95 C... Stop trolling

[jimmycaille]

So false reading, can't be other thing if the heatsink is correctly fixed.

[nocturnus]

Prolimatech Genesis (no fans), Phanteks PH-TC14PE (bad fans) and Thermalright Silver Arrow (good fans) all get better results than this 3 year old oldtimer. Even better results, than this wannabe-watercoolers from corsair...

You couldn't be further from the truth:

The coolers you mentioned are pretty good, but Corsair's cheaper Hydro series WC unit outperforms them by quite a large margin. The H100 lays waste to them. Personally I'm running at 4.8ghz IB 3770K with 35° celcius idle and 70° celcius FULL load temps with the H100 set to medium.

OP

The first thing you should do is reset your BIOS and check your voltages. If the problem persists, buy a new CPU cooler: Scythe Mugen 2 Rev. B is a damn good cooler, especially for it's relatively low price. The Noctua NH-D14 is one of the best air-coolers out there but costs twice as much. The Thermalright Silver Arrow is also an amazing cooler and is a way in between. Here's a review for you:

If the problem persists, you'll have to test your CPU on another motherboard. Just buy one and bring it back after having tested your CPU. You should be able to get your money back if you return the product within 24 hours.

Under full load (at least with SB) stock fans will flounder on anything above an i5-2300~.

I've tested a g620 and i3-2100 on stock cooling which never broke above 55c~ under prime95.

Then later on I tested an i5-2400 and i5-2500 with stock fans and I was lucky if it would stay under 85c after 5 minutes.

My i5-2500 with a 212+ now never gets above 54ish after 30+ minutes on prime.

There can be 2 sides to this coin. A - The heatsink is not seated properly or B - The temperature reader is wrong. Even if you're using the stock heatsink the temperature shouldn't go passed 60C. I've build many computers with the stock heatsink and it works just fine (as long as you don't overclock it).

Considering I've tested numerous stock coolers as stated above, on 4 different processors (with arctic silver), I strongly disagree. Hell, my hyper 212+ still hits 54c~ under full load in prime95.

I'm not sure what processors you're testing, but i5 and up there's no way in hell it's going to stay "below 60c" under a stress test like prime on stock cooling. Dual core SB/IB? Sure. Definitely not quad cores.

If you've never installed a stock intel cooler before, you may have done it wrong b/c they're a pain in the ass.

No, I certainly know how to.

Read down to where that reviewer's temps sat after stress testing on stock cooling. There's seriously just no way to achieve below 60c under full load on 1155 quad cores. If it WAS possible, there would be absolutely zero reason for buying aftermarket cooling for overclocking, considering max TDP of 1155 is 98c.
