i7 7700k 91c temps. help?

carsonn549 · Feb 26, 2018

Today I was curious to find out what temps i get on my cpu and gpu. I installed HWMonitor and RealTemp. When I was browsing the internet I got around 51c-55c and when I was gaming I got 80c-91c. I researched a bit and I found out that these temps are extreme and dangerous.
My rig:
ASUS TUF Z270 Mark 1
Intel® Core™ i7-7700K
ASUS ROG Strix GeForce® GTX 1070
Corsair Vengeance LPX 16GB DDR4 2400MHz C16
HDD Seagate BarraCuda 2TB
Samsung 850 EVO 250GB

What could I do to bring down my temps?

The thermal interface material (thermal paste in between cpu die and metal IHS) isn't that great on those chips, what cooler do you have?

smashjohn · Feb 26, 2018

Seems hot to me, but these chips are notoriously hot. Intel puts the thermal limit at 100C, so I don't know that extreme and dangerous is accurate. Lower temps can probably be achieved with a better cooler. I'm a big fan of the Noctua NH-D15.

Nothing can be thought about until you've told us what the cooler is, those CPU's need a 130W cooler to run at stock, and that would keep you just inside thermal limits, which is where you are. So you need a 180W+ cooler to run below limits or quietly.

funnkyspider.tudardio,

On behalf of Tom's Moderator Team, welcome aboard!

Although Throttle temperature (Tj Max) for the 7700K is 100°C, it’s not advisable to run your CPU near it's thermal limit, just as common sense tells you not to run a vehicle with the temperature gauge pegged in the red "hot" zone.

If your hottest Core is near it’s specified Tj Max Throttle temperature, then your CPU is already too hot. The consensus among well informed and highly experienced system builders, overclockers and reviewers, is that cooler is better for ultimate stability, performance and longevity. Experts all agree that it's prudent to observe a reasonable thermal margin below Tj Max.

Here's the operating range for Core temperature:

Core temperatures above 85°C aren't recommended.

Core temperatures below 80°C are preferred.

Core temperatures increase and decrease with Ambient temperature.

Many Forum Members often start temperature Threads without mentioning Ambient temperature, and responding Members frequently don't ask. You might live in the arctic or on the equator, so Ambient temperature is a huge variable that can range from 10°C to 40°C. Standard or "normal" Ambient (room) temperature is 22°C or 72°F.

Q: What is your Ambient temperature?

Also, you might want to include this in your research: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

So we should guess what if your temps are normal or above normal without the cooler type being listed, or ambient temps?

mdd1963 · Feb 26, 2018

for reference, my gaming temps with 7700K (4 cores at 4.5 GHz) under Battlefield 1 run about 64C using a Noctua NH-D15...

carsonn549 · Feb 27, 2018

This is my cpu cooler CYTHE Katana 4 SCKTN-4000 and my ambient temp is usually 22c

Only 92mm fans, gut feel is its not enough

crackz · Feb 27, 2018

Have you applied the thermal compound yourself?

@down:
If you put too much thermal compound you can toast your CPU

13thmonkey · Feb 27, 2018

crackz :

bad compound to perfect compound only makes 5-6C of difference.

carsonn549 · Feb 27, 2018

crackz :

I had my friend help me (he builds pcs so I guess it's correctly applied). The compound came with the cpu cooler so I guess it's pretty poor. I live in Romania so idk how I could get good stuff..

carsonn549 · Feb 27, 2018

Also my pc is under my desk. I think the hot air might be somehow getting sucked through the front fans so imma try to move my pc in a more open area and see if it improves the temps.

13thmonkey · Feb 27, 2018

Best to worst, makes very little difference. http://www.tomshardware.co.uk/thermal-paste-comparison,review-33969-10.html

carsonn549 · Feb 27, 2018

This is where I could buy from https://www.pcgarage.ro/pasta-termoconductoare/ . Could you recommend me a compound?

13thmonkey · Feb 27, 2018

carsonn549 :

It's not a compound problem, your cooler is not big enough. I know that he's telling you what you want to hear, doesn't mean it is correct.

carsonn549 · Feb 27, 2018

Ok then, what cooler should I buy?

13thmonkey · Feb 27, 2018

carsonn549 :

Cryorig h5 or better in my opinion

smashjohn · Feb 27, 2018

I really like this paste: https://www.pcgarage.ro/pasta-termoconductoare/noctua/nt-h1/

This is one of the best coolers on the market, but it's really tall. You have to check measurements of your case to make sure it will fit. Also make sure it won't hit your RAM: https://www.pcgarage.ro/coolere/noctua/nh-d15/

If you need something smaller, this works pretty well too: https://www.pcgarage.ro/coolere/be-quiet/dark-rock-tf/

I think the Cryorig is probably great too, I just haven't used one.

carsonn549 · Mar 5, 2018

I have this case http://www.sharkoon.com/product/1678/M25-W#desc . It says it supports 167mm cpu cooler height and the noctua cooler is 165mm. Should I buy the be quiet! one?

Also how could I see if the cooler would hit the ram sticks?

crackz · Mar 5, 2018

https://www.bequiet.com/en/cpucooler/482

You have to measure the size of your RAM and the cooler.

carsonn549 · Mar 5, 2018

Ok I found this https://www.bequiet.com/admin/ImageServer.php?ID=78491a1458@be-quiet.net&.jpg
Which measurement should I take in consideration?

smashjohn · Mar 5, 2018

I doubt that will have trouble fitting, but in general you're checking the total height to see if it will fit in your case and RAM clearance to make sure it won't run into the memory sticks.

carsonn549 · Mar 5, 2018

I found out my ram sticks are 34mm so they fit without any problems. Should I get the Noctua NH-D15 or the be quiet! Dark Rock 3 Pro and get a whole new bigger case?

carsonn549 · Mar 11, 2018

I bought the noctua nh-d15 and it fits in my current case. Thanks to everyone that helped me with this.
