Temperature Advice

[Miko_]

Hi there! I have put together a computer recently, and decided that I would like to Overclock it for better performance. The CPU is the Intel i5 4690k (3.5 GHz). I oc'd it to 4.3GHz and ran a stress test on it. Everything seems good except the peak temperature worried me a little.

 

At one point one of the cores reached 82 degrees Celsius. Is that safe? I don't plan on using this computer for any heavy workload that would need to use all the cores on 100%, it's a gaming oriented budget build (my first, so probably pretty meh). Would increasing the Voltage lower temperature? Or does it have no affect on it whatsoever? Buying new parts is currently not an option. I would prefer to keep it at 4.3GHz, but if necessary, I could lower it.

 

The stress test was very short however, I plan on leaving the computer overnight and I will make sure to post any updates. Any help is greatly appreciated.

 

Cooler: Cooler Master Seidon 120V.

Voltage: 1.122V.

I tend to try to stay under 70, with my h100i.  I would not recommend going over 75 encase there happens to be some airflow what dust build up that makes it go higher.What cooler do you have?

[AlwaysFSX]

82C is safe but you should try to keep it under.

[Chronos5618]

Increasing the voltage will increase the temperature. Try decreasing it to reduce temps.

Of course, how could I forget. Cooler Master Seidon 120V.

That's pretty high for 4.3ghz only, but in order to properly say anything we need more information. Voltage, cooler, programm used for stresstesting.

ah forgot , whats the ambient temperature in the room?

20.

 

Also, I lowered the Voltage to 1.122V.

[Luc401]

20.

 

Also, I lowered the Voltage to 1.122V.

make sure to run a stress tester after making any changes.

Sorry, I'm new. From 1.136V I believe. I'm running a test overnight.

82 deg on 1.136V? Your cooler must be improperly installed... Since you have devil's canyon the TIM caveats apply to a lesser degree and i can compare it somewhat to my delidded chip.

I get 74deg at 1.173V (4.2ghz) in Intel Burn test, and that is on a very small 92mm NH-U9S noctua cooler with fan at 12.5%.

Are you using manual voltage or another setting?

With any setting but manual voltage, synthetic stress tests will pull more voltage than you set it to, and will increase temperatures accordingly.  

82°C isn't too hot, but it's high, especially for 1.136V.  If your processor starts getting into the 90's, then you want to change something immediately.  

 

Also, what programs are you using to monitor temperature and voltage?

Manual Voltage, also using prime95.

[Queek]

Manual Voltage

Good 

 

 

also using prime95.

prime95 tends to get devil's canyon cpus very hot.  Try AIDA64 and you'll probably find your temperatures are much lower while stress testing.  

[sgloux3470]

My rule of thumb is that stress test can hit any temperature as long as they don't hit the Tj Max.  Regular usage will never reach similar temperatures, and will be in a perfectly safe range.

 

Intel chips don't even start throttling until well past 82 degrees, you're fine.

That's way too high for that voltage, shouldn't be higher than 75C at 1.122v, you would get better results out of the stock cooler if it was mounted correctly.

Things to try:

1) Make sure the pump is plugged into the PWM fan header on the mobo labeled "CPU_FAN", go in your BIOS and make sure the pump is running at 100%.

2) If the pump is running at 100% you can try increasing the fan curve for the radiator fan

3) If the above steps have resulted in no change make sure the pump has a solid mount on the CPU. If you have removed the pump at any point without changing the thermal paste you should remount the pump, making sure to clean off both the CPU and pump block with 99% Isopropyl alcohol and reapply new thermal paste. Too much thermal paste is often times worse than too little, uncooked grain of rice sized strip down the middle of the CPU is all you need (perpendicular to the text printed on the CPU).

 

Just to clarify, 82C is not a dangerous temperature, it's just at anything less than 1.2v I would never expect a Devil's Canyon chip to get above 75C, unless you're using Intel Burn Test to bench it in....in which case, stop and use something reasonable like Intel's XTU. Maybe you're using Prime95 and adaptive voltage instead of manual? I really can't see how you're getting that high of temp barring those circumstances or an improper block mount/configuration.

its normal for prime 95 to overheat the cpu dont worry the temps will be way good under regular daily/gaming/lightwork conditions.
