2500k temps 15% higher after 2 years

[The Green Bean]

When I got my 2500k (Hyper 212+) back in 2011, the load temps were 65 @ 4600mhz 1.375v. Now I'm getting 77 under load @ 4300mhz 1.375v. The case is relatively dust free. Ambient temps are similar. The only thing I've changed is a GTX 470--> 7950 and upgraded to Win 8. The casing is also in a slightly less open area. It was open on three sides back then. Now it's in a corner.

Don't remember the old idle temps but I'm getting 37 with 33 ambient temps.

1) Are the temps too high?
2) Should I try reseating the HSF?

 

[ArsenalGear]

Case is dust-free but what about the heatsink? I'd remove it, blow all the dust out, reapply the thermal compound and reseat it. It that doesn't help, maybe try updating BIOS to a newer version?

 

[Kenmitch]

What TIM did you use? Some of them will degrade over time more than others.

 

[KingFatty]

Re-applying the thermal paste may solve the issue. NOt just because the past may degrade over time, but also the paste may be "pumped" out due to many heat cycles where there is migration of the paste over time.

 

[fixbsod]

Do a thorough dusting inside and out, check that your fans spin fine (I've even dusted the blades with q-tips), TIM as noted due to degradation/pump out. Also make sure your voltages haven't changed tho it doesn't sound like it. Are you running your memory more agressive? With the IMC I noticed higher load temps @ 1866 vs 1600 around 4+- degrees C.

That's what I would try first, too. Any dust caked on the fan(s) or heat exchanger fins will reduce the cooler's efficiency... and it may not look like anything is there, but you would be surprised.

Not really... it depends on your ambient temps and how well the case fans can move the air through the machine. My 2500K (@ 4.1GHz) idles at 30-35C, sometimes as high as 37 if it's in the heat of the afternoon (my office faces west and gets the afternoon sun; ) I've not found my chip to be a very good overclocker... high temps being the limiting factor... I believe I just got a hot chip.

temps 15% higher

That's not how Fahrenheit works.

OP's using Celsius. You might want to put on a pair of glasses.

The statement is still incorrect. If you wanted to say that a temperature was 15% higher you should only be using Kelvin. The statement is nonsensical in anything but.

I digress though - as others have stated, the temperatures are still well within tolerances. If you're concerned, clean out your fans properly (hand cleaning with q-tips and kleenex) and reapply some new TIM. That should get your temperatures back down to normal.

The lack of available airflow might also be causing you issues. An easy way of checking this would be to move the exhaust away from any walls that are close by (side panels usually don't matter, and side vents often decrease airflow performance).

If you're going to be a pedant, is it not advisable to be correct? DS made a big fool of himself.

There was no functional difference between the two. L2transitive property of equality.

However you'd like to play off the fact that you can't seem to read.

1. quickwin : move it out of the corner and see if temps fall
2. How close to the cpu is the new 7950 seated? I've burned RAM by having it too close to a gtx580

 

[Tattoedsailor]

I got same processor (3800mhz). My temps are:

Idle 29-31
Load 45-50
Ambient 21

CM v8 Cooler

Just tested the load with HM and Metro 2033

I thought about upgrading to liquid cooler but not sure if its going to make a difference

However you want to play off the fact that you weren't quick enough to notice that there's no difference, and so leapt before you looked.

Did the 1.375 Volts fry your chip a bit? 4.3GHz on the same chip that got 4.6GHz. You might PM Idon'tcare about it. He has run Voltage vs temp testing on CPU's including the 2600k.

There is a difference. One's spelled F-A-H-R-E-N-H-E-I-T, and the other is spelled C-E-L-S-I-U-S. They are also two different temperature scales.

It's amazing that you've managed to make your way onto these forums without ever being educated on the difference between the two most common temperature scales used in the world.

 

[Sleepingforest]

Do we really need to fight each other over pedantry?

Anyway, OP, try looking at the heatsink, fans, and thermal paste. A problem in any of those would heat up your CPU more than before.

IME putting the machine in a corner makes a very big difference. I have mine in a corner and I had to put it backwards ie. rear facing forward to get proper cooling. What I think happens is that the intake gets warm air from the PSU (my PSU is bottom mounted). It made a huge difference in temps and overclockability to just face the rear forward. Of course what everybody else is saying is true about dust in the HS and TIM degradation. The simplest first test is to move the machine.

 

[FalseChristian]

It's just a degradation of the thermal paste. It needs to be scraped off and replaced. I've done it with my i5 2500K at 4.5GHz twice in 1 year.

 

[Binky]

The old temps sound suspiciously low. Is 65C load @ 4600mhz with 1.375v reasonable to expect with a Hyper 202+?

 

[guskline]

I use Intel Burn test to check max temps. I also agree that TIM needs reapplied. Buy 91% Isoprophyl alcohol to clean the cpu AND the cooler and be sure both are perfectly clean before reapplying thermal paste.

 

[guskline]

Do you use 2 fans on the Hyper212+ for Push/Pull? If not you might want to try it. It helps with temps.

 

[Obie327]

I understand the frustration when the heat is on. Have a phenom 940 in a secluded tight spot. Tower/Rig placement is very important in your situation. Seems like that corner isn't helping your situation much. Three sides are blocked also making things really toasty. I'm running on a Sandy 2600k overclocked but open on almost all sides. (using two folding tables and tower in middle of them) My experience in dealing with so many computer/heat related issues with others is placement And or shock damage. I use Artic Silver 5 exclusively for years on most builds for clients,friends,mine. Never had to reapply tim if done right. (Some going on 8 years of age now) Cleaning out system is a must but also making sure system isn't sitting on floor blocking intakes etc. If you decide to leave Rig where it at then increase intake and exhaust fans to compensate or even turning on a fan that can suck out any extra heat in that corner spot. Sometimes even a new case with a better design for your location can do wonders. Good luck

Are you using the same BIOS version and the same program? I've noticed that some BIOS versions tend to alter the read outs of the temps. Happened on my Q9550 and P5Q Deluxe a few years back.

Also the software you are using may have updated the TJmax, thus giving you a wrong delta.

Your gpu could be also at fault, if you jumped from a radial type HSF gpu to an axial type one.
