i7 6700K Temperatures?

[Bullivent]

Hello,

This is a fairly new system I built and its used for a lot of gaming, Nothing in it is overclocked and It's running an i7 6700K with a Corsair H100i V2 cooler. I Always keep HWMonitor open to check temperatures, and today I was gaming on high settings and at one stage my CPU hit 89 degrees, One core even hit 91! I feel like this is a tad too high, Expecially with a water cooler.

I may be wrong and this could be normal but could I get your opinions on this?

Also while I am here, Could you give me your opinions on my Asus Strix GTX 970 Temps, It hit a max of 75 degrees in the same session, is this within normal range too?

I have attached a image of HWMonitor just for reference.

Thanks in advance!

That's hotter than I would expect, but isn't going to damage anything. Have you ensured that the pump is running at full speed, and that the block is mounted properly?

75-85c is very normal for a modern GPU.

My 6700k has never exceeded 75C even when stress testing with CoreTemp. In games it reaches around 66C at max, usually around 60C. I'd recommend seeing what your pump and fan speeds are set at, as well as making sure the block is mounted properly.

If that doesn't work, I'd suggest taking the block off your CPU and reapply the thermal paste, and then make sure it spreads well so your full CPU is covered.

As for GPU, most reach their thermal threshold between 80-90C. Try turning your fans up if you can.

Temps are way too high. My 6700K at 4.6Ghz wont exceed 70C on a core unless I run IBT and Prime 95 small FFTs at the same time. I'm using a Phanteks PH TC14PE. Your H100i should about equal or maybe even beat my cooler by a degree or two.

75C on a GTX 970 is fine.

Reinstall your cooler. If that doesn't work then your pump might be failing.

The Pump feels secure, However I have not been able to take it off and re-mount it yet. I do run the pump as well as the fans on the rad in quiet mode so the speeds are on the lower end compared to performance, this is because in performance mode the pump makes a very annoying buzzing sound, Should I be getting these temperatures even with the pump in quiet mode?

Also when I reinstall the cooler, do I have too change the thermal paste or would I get away without? I don't have any spare paste and It's still using the pre-applied paste.

Hopefully when I do reinstall, it will solve the issue, if not what should be the next step?

Good to know my GPU is within good temperature ranges though,

Many thanks!

Try the pump in performance mode and see what happens!

Ideeally you should generally change the paste whenever you separate the CPU and cooler, but I've skipped this on occasion when the paste still looked very wet, and like it would make a good seal.

This is why I generally don't like AiO watercoolers - there's a lot more to go wrong with a tower cooler, they're nosy, more expensive, and perform worse.

Louder and more parts to fail, yes. But starting with the H100 and up they perform as well as or better than the best air coolers. I don't use them either and wouldn't but they do perform well and they look good.

I clicked best solution by accident so if a mod could deselect it or something I would be greatful.

Although it is correct that it's more to go wrong, they still have good cooling performance I think, and the main reason I bought it to be honest was because of asthetics, air coolers are more reliable but in my opinion they don't look the best.

I did the same thing tonight, I was going to put the pump in performance mode but I completely forgot, however max temperature this time was 88 degrees, still high!

Tomorrow I will make sure to try the pump in performance mode to see if it makes a difference, however I might purchase some thermal paste tomorrow aswell just Incase, it won't hurt to have a spare tube lying around anyway, anyone know what the best thermal paste to go for is? And what should I buy to remove old thermal paste?

I will update the temperatures tomorrow with performance mode on and see if it makes much of a difference.

Arctic Cooling MX-4 or the Noctua or Phanteks branded pastes. Those are among the better performers and are relatively cheap.

I use coffee filters and rubbing alcohol to clean off old paste. No lint to worry about.

Then a small dot about the size of a pea is all the paste you use. More is not better.

Your temps are high enough that either the cooler is secured to the CPU wrong, your fan setup is completely wrong or your pump is failing I believe. I'm sitting here at 4.6Ghz idling at 23-27C. I see the mid 60s gaming. Your H100 should be very similar.

For some reason it keeps picking best answer when replying using my phone, if you could deselect it once again that would be great

I was on the game for at least 5 hours tonight, constantly checking my temperatures, and on performance mode they only hit a high of 64 degrees, that's a pretty big drop! The only problem is the pump creates a lot more noise with the faster speeds which bugs me quite a bit.

Do you think I should still be worrying after these results? I don't know if those other results would be normal for quiet mode. Should I do something else or just leave it as it is for now?

I didn't think performance mode made that much of a difference but 64C is perfectly fine when stressed. One of the bad things about all in ones is the noise they make. That's the main reason I wouldn't buy one myself.

 

[Bullivent]

I didn't think it would to be honest, although I think it is over 1000rpm difference and you can definitely hear it, I didn't think AIO's made any noise to be honest, this is the first one I've ever had.

I think you could try different combinations, performance mode puts both the fans and the pump into that mode however I could maybe try quiet mode on pump and performance on fans, or vice Versa and see what happens, I will test it tomorrow and give an update, but I agree 64 degrees isn't bad at all, do you think there is anything more I should do with the pump that isn't software related or should I just leave it all as it is for now?

 

[Deleted member 217926]

As you say, just experiment and see what you can do with the various modes.

However; in all of the reviews I've seen the difference between low and performance mode is only ~5C - ~7C. You're seeing 20C or more. That's too much. These reviews are all from when the H100 was released and they may have tweaked it since but your variation is just too high.

I still think something has a problem.

 

[Bullivent]

I was on the same game tonight, everything the same apart from I changed pump from performance to quiet and left fans on performance and the highest temp was 68 degrees, I don't think that's too bad overall, that's a 23 degree drop.

The fans I have on my rad are SP 120's QE PWM, QE means the fans RPM's are lower in the first place, and I think The problem may have been the fans were not cooling the liquid quick enough causing huge temperature increases.

I'm starting to worry less now, do you still think there is something wrong and should do more tests or should I just call it a day with it for now?

As long as you're happy with the temps then there's no reason to do anything else. Just monitor them from time to time to make sure they are staying consistent.
