Different core temps.... RMA?

[shbris]

even with water you can't cool below the ambient temperature of the room, so his/her room must be below 15'C!!

[dagwoood]

Indeed but even the best watercooling in the world you cant drop the temps below room temp, which is apparently 17oC or less. Average room temperatures are normally 20-25oC hence his room seems rather cold

Hehe, I knew that guys, I assumed he'd got a rad sticking out of the window or something

Doesn't sound unreasonable to me. I only maintain my house at about 17 - 18 degrees when the heating's on! I regularly get room temps of 14 - 15 degrees (I don't sit in them for very long at that temperature, mind...).

Also, it's possible that a room, and therefore the water in the system, dropped to a significantly lower temperature overnight; and as we all know water has a very high specific heat so would take longer to heat up to ambient than the air in the room (although in that case, it means that the water-cooling would actually operate as water-heating for a short period!).

mines just under 3ghz and temps as follows
22
22
15
17

lol - that's gotta be sub-ambient, unless you don't have any central heating.

you have nothing to worry about, 1 of the dual core is having more use than the other, so 2 cores always read higher

up have to remember its 2 core2duo's on 1 chip

Exactly, and they may even be from different batches/wafers for all we know, and thus have quite a large difference in running temp just due to the vagaries of the manufacturing process.

The most likely reason for GoNz0's temperatures is that CPU thermal probes are not always very accurate.

[GoNz0]

nah its quite accurate im glad to say, reasons it was so low.

heating was off all night, (were in bed so its not needed) the pc rooms rad is set to frost as the pc warms the room after an hour or 2 and the heating had only been on for 30 mins

the room was at a guess 12 degrees when i came in this morning and booked my returns for work, it felt bloody cold anyway !

after an hour min core temps about 20 degrees and it gets up to about 25 idle after a few hours.

yeah my q6600 runs at 33/31/28/27 idle and 52/48/45/39 under load. i was a bit concerned at the huge difference between the cores at first but it never goes past 52 and runs perfectly stable so i just left it.

[Tonka777]

My Q6600 @3.0Ghz also runs with ~10 degrees difference between the two pairs of cores. I dont think the OP has anything to worry about.

[GoNz0]

they tend to even up on a burn in test as well

Does lapping actually work? I cant imagine there be much of a temperature difference from removing <0.5 mm from the top a cpu

It does, but I still wouldn't do it.

you don't actually achieve the extra cooling by shortening the distance the heat travels, it's by making the top of the CPU much flatter than it already is so that the contact between the CPU and the HSF is better.
