Normal fluctuating temps for a 3770k?

post #1 of 3
Thread Starter 
Assembled my custom loop 2 weeks ago and decided to finally do some overclocking.

My 690 is nice and cool @ +150Mhz core, max 45c.

But my CPU is a different story, i need about 1.280V for 4.5Ghz.

In LOAD my temps is like this:

Core0: 71
Core1: 80
Core2:86-87
Core3: 82

And in IDLE the temps is like this:

Core0: 33-40c
Core1: 25-29
Core2: 24-28
Core3: 26-30

Ambient about 19-22c

How can the coolest core in LOAD be the hottest core in IDLE?

I've remounted my EK Supremacy about 5 times with different TIMs and i've also checked the block, it was not curving inward.

What is the next move to try? Is deliding my only option?





EDIT

The hardware is 120+200+240 Rads, D5 pump with ek top, 13/19 tubing. The pump is at the highest speed (5)

The order is as follows, Res > Pump > GPU > 120 Rad > CPU > 240 Rad > 200 Rad > Res

That's because of the bad thermal interface between the die and IHS. My 3770K was similar, also at idle core 0/1 was loaded the most so should be hotter. At load the differences exist because of unequal die contact

Yeah i was afraid it was like that, the temps with stock clocks is stable, but as soon as i overclock it, it goes like above.

Well, the next step is probably deliding it then, bought some Coollaboratory Liquid Ultra last week so i only need to find a vise and im ready to go!
