difference in temps on each core

mcgriffo · 16 Apr 2008 at 12:45

out of interest - is it normal, and why does it show it like this, to have a 5 degree difference in temps between core 0 and core 1 (on a dual core)?

eg core 0 = 19c
core 1 = 24c

?

Not sure on a dual but on my quad the cores vary by up to 5deg. If your really bothered you could do some laping.

Its the concave IHS that intel insist on using, Lapping the CPU fixes it - but may damage resale value.

The cores on my quad vary by around 3 C but which core(s) are cooler/hotter seems to vary everytime I check. I have lapped both the CPU and HSF though.

Mine are normally within 1deg of each other, but I have noticed that 1 of the cores shows more load than the other quite often.

3c difference between my cores. Generall 0 & 1 are hotter than 2 & 3.

Lapping my CPU reduce the diff by a couple of C. Lapped my old Ultima 90i and that was 4c ish out. The new Noctua (not lapped) is better for contact...

5c is nothing tbh.

I have a 5c difference in my cores, pretty much whether the cpu is under load or not.

Current idle temps are 32c 31c 27c 30c

Apparently this is normal!

Mine are 3-4 degrees apart. Idling at 33, 36/7

Remember that only measures taken when all cores are in use are valid, if running a single process thread, one core's always gonna warm up a bit more.
