CPU Very High Temp 105C

Hey Guys.

i have corsair h100 water cooling kit for CPU while i was playing tomb raider i felt so much heat coming out of my PC so i exit game and and check RealTemp and it was on freaking 105C :fou: lol damn thats fuckin hot is my corsair is gone or what? and one of the cores say "LOG" others are OK in real temp look at the screen shot below

  1. Have you checked that the h100 is mounted correctly and securely?
  2. yeah it was perfect im using that from around 7 months its just this evening it went so hot!
  3. Is the pump working? Is the water actually moving around?
  4. yep, something is definitely wrong there.
    1) check that your pump is working. If there is no water flowing, then it won't do you a whole lot of good.

    2) check your cooling fan. If the water is pumping, but there is no active cooling then you will have a slow ramp up, and a slow ramp down of heat buildup.

    3) check thermal paste. Too little and you end up with air pockets that cause issues, too much and you end up with an insulating blanket, none at all and you can't get a proper surface to contact the 2 plates.

    4) check your mounting. you need a fair amount of pressure to make a good contact. A lot of these newer boards and coolers require an uncomfortable amount of pressure where you may think it will break something.

    5) lastly, check your overclock. It is quite possible that your voltage is simply too high.
  5. how would i know if that pump is working lol.

    my voltage is quite ok i guess its 1.280V clocked @ 4.0Ghz

    what about that the "LOG" thingy on one of my cores in realtemp is something bad for my processor?

    btw this are my PC specs.

    Asus Maximus V extreme
    intel i7 3770k clocked @ 4.0Ghz
    AMD HD 7990 + 7970 Crossfire
    Corsair AX1200i
  6. I'm not familiar with this kit but I guess you should be able to hold one of the tubes/hoses and feel a slight vibration from the liquid pumping around. Also the tube going to the CPU should be colder than the one going from the CPU.
  7. LOG just means that it got to a dangerously high temp and that it made a log of it.
    Anything over 1.2V is a bit high, and 1.3V is the absolute max you want your voltage to be at to run it safe and reliably for any length of time. If I were you then I would try and bring it down to a sub 1.2V if possible just to add some longevity to your system, but this is not likely the issue that you are running into right now.

    Pumps are quiet, but by no means silent. Open up your case, put your hand on the pump, power on the system, and try and feel or hear if the pump kicks on with the system.
    Same goes for the fan, give it a visual inspection to make sure it is going somewhere.

    Not really true. Water cooling systems work with much more average temperatures because the water moves so quickly through the system. The entire loop gets warm to a point of saturation as the temperature rises, so there should be little to no difference between the temp before or after a heat load (or at least not one that you could feel by touch).

    Vibration or sound would let you know if it is working or not. Or if your CPU is pegging 105*c while the radiator is still relatively cool to the touch would also imply that water is not flowing.

    i just felt a bit vibration on pump when i power on the system so i guess pump is fine. but it was all working perfect i did not even open case or change anything last time i did was around 2/3 weeks ago to add GPU's and it was wroking great until tonight so i guess that pump might not be working well because i don't see any other problem

    one more thing i just again did some stress test on CPU and radiator went super hot!
  11. Well if the radiator is hot that's a "semi" good sign because that shows that heat is being distrubed correctly from the CPU to radiator. It sounds like the fan(s) in the radiator have stopped working since it cannot get rid of the heat.
  12. Best answer
    1) While troubleshooting your cooling, GET rid of OC and lower your Vcore.
    .... Your OC is just Barely at the point of noticing it. Your CPU is 3.5 w/turbo of 3.9 so NO effect on single threaded app and for Multi threaded apps it on represents a 14% bump and it takes from 10->15% to even notice the diff.
    Case in point, My lowely i5-2500K runs fine up to 4.8 On air HSF- Zalman 9900Max Temps <70C runing prime 95), but dropped it to 4.2 as I could not see any real life day-2-day difference.

    ... You indicate hitting 105C so you should also see a DECREASE in CPU speed as throttling starts at 100C. complete shutdown should occur at 125C. Operation @ or above 80 C will not kill the CPU but will decrease life expenancy. Continuous operation for prolong period of time, I recommend no higher than low 70's

    ... Vcore of upto 1.35V should be OK providing temps do NOT go above 70C. But agree with CaedenV, I prefer 1.25 or lower.

    For TS H20 Cooling, CaedenV is more knowledgeable then me - I've had good luck using Air HSF: Zalman 9500LED (on e6400 @ 3.2), 9700 LED on i5-750 at 4.2 and 9900 Max on i5-2500K upto 4.8.
