Is my 4770k temperature normal?

[BlackWing1977]

I tried Prime95 and the temperature hovers around 80 ~ 83 degrees at stock, but turbo to 3.9Ghz at load. No overclock. Idle around 40 ~ 42

I am using Noctua NH-D14, do I need to clean the TIM and reapply and re-seat the cooler??

Because when I first install it... I was in a hurry, just squeeze a dab of the TIM and never spread it, and then I put the cooler on and screw in liao.

My casing is a old HAF-932 but recently cleaned thoroughly and replaced all the casing fan. The front was replaced with a CM Megaflow 200mm Red LED, and the top exhaust and side intake is using Megaflow 200mm fan, and rear exhaust is using Corsair 140mm fan.

I don't own a 4770, so I can't comment on your temps but have you checked whether the room housing the tower has airflow?
Placing it in a corner without the windows open can cause bad temps.

What is your ambient temp?

 

[Phelan]

Way too high for what you're using. I am running a 4770k on the stock HSF (RMAing something my AIO). Normal usage goes to 50 tops. Running AC4 hits about 74. My case temperature is about 32 to 34.

Best is to resit the HSF. No need to spread the TIM as you apply it since the pressure of the contact will spread it for you. Only thing to note is the amount and how you squeeze it along chip.

consider normal, though most old bird here will tell you its too high. do you run 100% on most time when you use your pc?

few factor affecting your temp

chip quality
room temp
sg weather
case air flow
different heatsink/TIM giv different temp

try wc the cheap version first if fits your budget (my 4770k is on custom wc, idle 32, full load 68, ambient temp 30deg)

get spyboy to delid for you at a fee, note warranty

I am using HWMonitor to read the temps, what software you guys using??

Mine is similar setup as urs...temp is aound there...also stock freq

So probably dun need to do anything liao... just leave it at stock... since probably most games I play wun benefit from any high clock speed liao.

Monitor for a period. After tim cure time might hav slight imrpovement.

although I'm not using the K version it's a 4770 SKU.

idle 24C
Load after Prime 60C
Intel IBT - 65C

hardware on the right..

think you need to reseat your HSF as it does appear to high.

btw, my ambience is around 25C

 

[sHrike]

idle not possible to be 24. cannot be lower than ambience temp

It is very important to factor in ambient temperature. If you blast aircon, your cores will definitely be cooler.

And yes, I think Antiloop's readings are not accurate. Cores never dip below ambient unless some heavy watercooling (with coolant) / LN2 is going on.

 

[BlackSmokeInTheSky]

hmm i think u should at least try to re apply tim and resit the heatsink. my temps for my 4770k overclocked to 4.4ghz idles at 36-39 degrees and on gaming max at 74 degrees. using h100i though but the d14 shouldnt be that far off. consider the airflow in ur casing too

 

[Mythmaker]

Megaflows are terrible fans...

 

[maxsony]

re-sit your NH-D14 heatsink.. and check whether the both fans at the heatsink are placed the correct airflow direction or not .. It could be one of the factors.. Due to the fact D14 is still consider the king of air cooler.. it shouldn't give you that kind of load temp when at stock speed..

agreed.
Simple law of thermodynamics..unless his coolant is 23C and cooler otherwise no way man

 

[sHrike]

Btw I think nh d14 also not v efficient. My ambient is 28 .but idle is aound 36-39...should I resit too?

I check my MSI Command Center, it seems that all the fans are running at lower speed, so when I push the speed to max, it does give a lower temperature, but dunno why my core speeds to indicate 3.7Ghz at load, and in the command centre, only 1 core is 3.9Ghz the rest at lower core speed.

try something like Intel BurnTest program to stress test your CPU.
All cores should stay at 3.9Ghz at 100% on stock settings. Temps should be around 80-90.

If your 4 cores dont maintain 100% under IBT load, then your motherboard is throttling it because it not enough juice to maintain this type of stress which is bad and need to complain to Corbell.
