i7 6700k 4.8ghz 1.375v h100i v2 Temperature problem?

post #1 of 57
Thread Starter 
Hello,

Yesterday i installed my new parts:

i7 6700k
Corsair H100i v2
Corsair 16gb vengeance lpx ddr4 @ 2666mhz
Asus Z170-A

My idle temps are completely fine 27c - 30c the coolant temperature is about 27c-30c.

I currently got a stable overlock at 4.8ghz with 1.375 volts but when i run aida64 the temps spike up to 87c and go straight back down to 60-70c for a couple of seconds then they spike up again. This keeps going on until i stop the stresstest the temps only stay at 87c for half a second or so. I use HWmonitor to read out the temperatures.
The pump is always running at full speed and the fans spinning at 780rpm. I don't really hear the pump but when i get close to my case i can hear a rattling noise and i can hear fluid pumping arround. When i touch the radiator under load it feels pretty cold is this normal? Both tubes are about the same temperature. I haven't touched my radiator when it was stability testing for a long period of time so i don't really know if the radiator gets hotter. Increasing the fan speed doesnt make alot of difference.

Thanks,

I've similar problems with my 670k with LC Kraken X61. But I'm getting those temps on lower clock.. It's probably caused by old, bad TIM. Take a look at this thread: http://www.overclock.net/t/1605898/6700k-temps-problem-question

Recently I bought that delid tool: https://www.youtube.com/watch?v=4o-rDGHZH4s and I'm waiting for delivery.

Yea, As stated above, I'd reapply the TIM and make sure its properly seated. If its fluxing that bad, may just not fitted well enough on the board

Good luck deliding! Im not going to delid not to comfortable with it to be honest. I managed to drop the temperature to max 80c by disabling SVID in the bios. I ordered 2 noctua nf-f12 industrialppc 2000 fans to mount on the radiator i guess that should drop the temp 1-2c.

TIM is the thermal paste right? Ill reapply some after i get my new fans. Im pretty sure its properly seated since my idle temps are really really low. I put some pressure on the the waterblock under load and it din't change the temperatures.

I got the H110i (280mm version of the same cooler.) and mine acts similarly. The fans sound like jet engines under load, too. Not very impressed about this cooler.

Oh the default fans are litteraly garbage... 37.5 dba at full load ridicoulous thats why i ordered 2 noctua nf-f12 industrialppc 2000 fans.

Im gonna change the thermal paste, maybe thats the problem you got no idea how old your unit is so maybe the thermal paste just got bad or something.

I would like to third the TIM (Thermal Interface Material or thermal paste) application as a solution, and also welcome you to the forums, hello! smile.gif

I would recommend Arctic MX-4 TIM, as it is very easy to spread and performs very well. Just in case you ever need to get some/don't think your current TIM is doing the job properly.

If after reapplication the temperatures still vary as you describe, the reason will most likely be a poor TIM application between the IHS (Integrated Heat Spreader) and the actual CPU die below it. To fix that you would have to delid, I hope this is not your problem so you don't have to go through that!

Gotcha! Seems like im definatly getting some new TIM. I should also add that i only hit those temps while stresstesting. While gaming/rendering the temps tend to stay below 72-73c.
