Erratic 4790K Temps

[Wiggyweir]

Hello all,

 

Installed my first custom loop a few days ago and everything seems pretty good actually except the temps on my CPU.

 

I used a EKWB Supremecy MX

Slim 240 Rad

 

if you look at a graph of the temps it peaks and drops ranging from the low 30s to low 50s idle very erratically, and peaks at around mid 80s under load.

 

When I installed it I used a moderate amount of paste but as my GPU is achieving amazing temps in the same loop I can only reach the conclusion that the contact between the block and CPU is to blame.

 

Any advice? Is it worth trying to re-seat the block with more paste? Is this going to be hard without draining the whole system? I’ve read that blocks sometimes have to be seated a certain way due to the copper fins inside but you can’t actually see into mine so I don’t have a clue

 

Cheers in advance

what does it hit when it is under full load? and what is it clocked too?

 

my 4770k is clocked to 4.4 and hits 85c+ on the same setup due to the crap TIM under the heat spreader. for me to fix it I would have to delid my CPU.

 

Low 50s is really good.

windows services eating up cpu randomly (happens with windows 10 on my laptop/desktop)

Under load it hits 80+ on stock frequency

if re seating the block does not help and the GPU in the same loop has no issues then it might be crappy TIM.

Im running a Phanteks PH-TC14PE on my overclocked 4790k and im seeing mid 70's during a stress test so yea you should be seeing a lot lower than that especially if its stock clocks.
