My New 7700K based PC is hitting 100C - Pls help

[MikeT_676]

HI,

i have recently purchased a system with the following config:

i7-7700K (not OverClocked) with intel CPU fan/heatsink (apprx $5 )
16 GB DDR4 RAM
Asus H170 -Pro Mobo
Samsung 500GB SSD + Seagate 3TB HDD
MSI 1060 GeForce GTX - 6 GB
Antec GX1200 Case
Corsair RM650x
7700K batch # L641G639


Whenever i play battlefield1, the temps are hitting 95C+ @ 4.3 GHz ( idle temps around 45C )


I also read somewhere that if delid this CPU i can get 30C lower temps (Which i really dont want to do as i fear i might damage the CPU)


im a total newbie coming to PC hardware. Pls suggest me a fix

Your case should be able to have 2 120mm intake fans at the front, 2 120mm exhaust fans at the top and a 120mm exhaust at the rear. Run the pair at the front and the other pair at the top with molex power cable to have them move the most air.

Yep also have the front fans pulling air in, top fans pushing air our as well as the rear fan push air out.

if i buy a new cooler, there wont be any use for the newly purchased CM 212 LED. i already had to buy 2 PSUs due to my lack of knowledge (one is sitting in my storeroom now)

Mike don't get discouraged. You replaced an inadequate stock heat sync with a less but still inadequate cooler master 212 evo. I tried warning you about this. Don't get me wrong, the 212 evo has served me well paired with my i5 2500k for many years.
That being said, max cpu cooler height for your case is 165mm.
I'd suggest pairing these cpu coolers with your 7700k:

In this guide don't get anything under the NH-D14.

Looks like my case needs more fans. i put a hand inside the case near the cabinet fans (2 Antec RGB fans) and didnt feel any air movement. right now there are 2 case fans + 1 CPU fan (CM 212).

Also, my ambient temps are around 30-35, so i cannot compare with most others

i just ordered 2 Corsair ML 120 fans. im hoping for some more improvement

Okay, if you've got the cpu cooler installed nice and tight and still getting temps in the 80's, lets look at your case airflow and fans. Look at your motherboard and count the sys fan headers, there should be 3 or 4. Are all your fans spinning fast when you power on the computer?

Also, as others suggested the prime version im using to test might be the reason

im using p95v2810.win64

im getting 80C when playing battlefield after installing CM212 LED cooler. (95C+ when using the intel sink-fan )

I see you have no exhaust fan. Flip your fan around so it's blowing the correct direction and add an exhaust fan in the back. Not having an exhaust fan will easily increase temps by 10c+ as the air has nowhere to go.

 

[MikeT_676]

Ok. added 2 corsair ML 120 fans today. And the temps have improved some more



However, i found out something interesting when trying to tune the newly installed Fan speeds. The temperate reported by Asus AI suite3 and HWMonitor seem to differ by more than 10-15 degrees

Temps seem to be a lot better. But the fan on your 212 needs to be flipped around for your airflow to make sense.

[MikeT_676]

All the 5 fans (1, 1, 3) are currently sending the air to the left side (from front of the case to back).

Do you still think i should flip the 212 fan?

I usually have the cpu heatsink fan push air thr the fins from the front side to the rear, then the exhaust fan exhausts that pushed air. A bad vrm on your motherboard could be letting more voltage get to your cpu than u want. Have you compared motherboard voltage settings to actual utilization using cpu-z?

Guys...the problem IS the 212 evo, no matter what position the fan is placed in. I've seen MANY posts of people stating high thermals with their i7 7700k paired with a cooler master hyper 212 evo. The evo simply isn't capable of cooling 4th through 7th gen intel core i7 processors.

He's getting temps of the mid 70's now that he added an exhaust fan. Full load for a 212 is pretty good. That's perfectly fine.

When placed under full load with prime95? I find that hard to believe. If his temps were that low, people wouldn't still be posting on this thread.

 

[dangus]

why ARE people still posting on this thread!? prime95 is not realistic anyways. who cares about prime95 temps....

i have a 4770k and a CM212 evo running at stock and it's just fine. never breaches 70C under load...in prime95....in games its at about 45C...so you're kinda wrong. sorry.

How much difference will i be able to achieve by using a Liquid Cooler like Kraken 62

 

[jwcrellin]

Probably like a delta of 15-20 degrees at idle and gaming vs 212evo.

 

[MikeT_676]

According this screenshot: https://image.ibb.co/eTFU6F/bf1.png
im getting 62C when gaming


do you have any real world comparisons between 212 and AIO? so that i can check. Thanks

[jwcrellin]

My i5 6600k is O.C.'d to 4.5 and my h100iv2, which is very similar to the Kraken, during AIDA64 stress testing, keeps me below 55'C.

You don't need to go with water cooler. You just need a larger heat sync. What case do you have?
