Such difference between core temps normal?

See image, is a 10°+ difference between cores normal? Fresh install of a Corsair H55 liquid cooling setup on an I7 920 OC'd to 3.2ghz+ with fresh thermal paste that's been running Prime95 for about an hour.

That's really not a big difference.

That said, it is odd that you would have core 0 as your hottest core. Based on the die layout of that cpu, I'd expect 1 and 2 to be the hottest and 0 and 3 to be equal.

It was this way with my old cooler, as well. That was a heatpipe cooler and actually did about a good a job as this liquid setup does (but a bit more noisey). Just something I've always found odd.

And for the record, not matter the cooler I've had, core 0 has always been the hottest.

Hmm. I'm not sure then. I wouldn't really be concerned though 10F really isn't a lot.

Totally normal.

It would look smaller in degrees C, which is the usual way to show it.

Crank it up, set bclk @ 180 & give it some more juice. It'll warm up

Ehhh for right now I think I'll be ok at 3.4ghz, Cities Skylines plays much better with the 6gb of RAM I just added that it would with another 200mhz. Although....no, no I'm good.

like everyone said, its normal
and yes core0 will be the hottest all the time

think it as primary/start core
cmiiw, even if os/software support multicore (multi threads), core0 will remain as prime core before using other core
i think it related to how programing work
i dont know very detail about this, maybe other can explain better
