When I check the temps of my i5 there is one core that is running about 20 degrees hotter that the rest!

core1 77f. core2 100f. core3 73f. core4 76f. at idle. I know that all are in range but why? Do I need to reset the CPU cooler? I

have the Thermaltake WATER2.0 Performer. Any Ideas. :??:

One core will run hotter than the others for some reason.

ye that is pretty normal. one of my cores runs about 15 degrees F (took me a while to realise you were talking in F not C!!) hotter than others as well.

whats it like at load? at load (gaming) in most games the temps are much more even i find.

I have seen some processors that have a core that will run as much as 10c hotter then the others. Most of the time one of them is about 5c hotter. It has to do the with the heat form the core next to it bleeding over to it. So core 1 which is on the edge will be one of the cooler along with core 4. Core 2 or 3 is generally one the hottest due to being between the others.

I thought they were like in a square pattern (the cores) not in a line if you get what i mean.

In case of Core 2 Quads it's square pattern( 2 cores on 2 dies.. basically a square),the later quad cores have a single row of cores sharing the same L3 cache.

EX: My quad's first two core temps are usally identical, 3'rd is about 5degrees lower and 4th is 2-3degrees lower than third core.

I ran prime 95 maxed out temps were all within 3 degrees, highest was 64c. The fans were whizzing louder than I have ever heard before playing any games so I think all is good thanks. It had me worried for a while. :wahoo:
