i7 7700k runnig hot?

So my PC spec are as follows;

i7 7700K not overclocked
h100i cpu water cooler (getting on the older side now, maybe 5 years or so)
GTX 1080 Duke
32inch 1440p 144hz curved monitor (felt like including this because of the load this monitor probably causes)
1TB SSD
250GB SSD
500GB SSD
32 GB DDR4 RAM
600W PSU
MSI Z270 A PRO MOBO

So whats happening is I felt like one day while I was playing BF5 my pc felt warmer then normal. So downloaded Core temp and monitored my CPU temps.
At idle my i7 runs at about 37-60 degrees
when i was playing my game I saw that the temps on my i7 reached 98 degrees. This was alarming to me. I know and heard these kaby lake i7s run warm but I feel like thats something I should be concerned about\

is it?

  1. Way too high, your pump may of failed on that H100i. Gaming loads should be under 80C for that CPU.

    thats what I thought.

    any way to tell if its running or not?

    Put your hand on the pump while the system is running, should feel a small vibration if it's working correctly.

    I cant feel it on the pump connected to the slot itself but i feel a vibration on the tubes for sure
  5. If memory serves me correctly Corsair Link should provide your pump RPM's, try downloading that and see if anything is at zero.

    If that shows that it's running then I'd thoroughly clean the system/AIO of dust then reapply thermal paste on the CPU and see if the temps go down. Also besides CoreTemp monitor the temps with HWmonitor just to double check them.

  6. i want to point out I also have a case thats probably not the best for airflow.

    https://www.amazon.com/gp/product/B01M6TV6PC/ref=oh_aui_search_asin_title?ie=UTF8&psc=1

    its a glass case.

    And I have both corsair link and hwmonitor. hw monitor is the same temps.
    and i only see fans under my mobo on corsair link not under the cpu section. only the core 1,2,3,4, package temps and load %
  7. Even with that case the airflow should be really good.

    okay so where should I see the fan rpm on corsair link? I dont see anything about fans under the cpu tab. only temps and load %.

    Also, just to make sure, is CPU_fan1 a good place to have the cord from the pump plugged into the mobo?

    I'm not sure, it's been quite awhile since I've used that program, I thought there was a option for the pump but maybe not.
  10. Many AIOs degrade in cooling capacity over the course of a few years of operation due to hard water deposits, contaminants, even algae-like build up, etc....

    (Some fluid blocks/pumps can be disassembled and cleaned when this is the case, however)
  11. So just for the hell of it I tried unplugging the whole cooler system to see if my idle temps went up and they did. They rose from the 40-60 degrees to 70ish. So it looks like it’s working?
  12. So I feel like a total boob.....

    I took off my cooler to check the thermal paste and possibly replace the cooler and low and behold the thermal paste was dry and crusty. Which was weird to me because it was installed maybe a year ago into this pc I built. I’ve had the cooler for years now.
    Anyway I thought it was weird so I checked my thermal paste box and the expiration or “shelf life” of that thermal paste ended..two years before I put it on...sigh..... what a dummy.

    Bought new thermal paste and now my idle temps ran in the 30s. And then I stressed the cpu with CPU-z and the highest temp was 84 degrees. Is that pretty good?

    I did buy a new h100i PRO cooler just Incase so I could do everything in one sitting...do you think I’ll get cooler temps compared to this older h100i v2? If so I may keep it and install it...
  13. After about 10 minutes they are jumping to the 60s at idle again...

    but i noticed the load jumps to 15% or so corresponding with this temp jump.

    if the load % is under 5% it stays in the 30s..

    sorry i know nothing of temps and what is normal

    84C for stress testing is ok, try a game and if it goes above 80C then consider using the Pro.

    so after about 10 minutes of playing BFV it does go from 77C to 82C. they jump around A LOT. i see 72C for a split second and 88C for a split second but they are generally within 77C to 82C
