Do some 2600ks run hotter than others at specific voltage?

post #1 of 11
Thread Starter 
my old 2600k at 1.55 ran just below 80C, however my new 2600k at 1.5voltage runs around 75C the same temp, is that normal? Or should i replace the chip with a different one? I was hoping it'd be cooler then the other, because i was needed 1.55 for 4.8, now i need 1.43, however i dont see a big temp drop. I re applied paste 4 times, and its MX4 artic.

Yeah, its normal to see some variation in temperature between two of the same CPU. I had a couple Q6600 CPUs back a couple years ago and one of them ran much hotter than the other (talking like 10-12C here).

It is normal to see variation, watch out with those voltages, however.

Do you have the same items in your loop as you did before?

What are the specific clocks you are using at these voltages?

It's not abnormal to see BIG temperature variations between these CPUs, like 10 degrees at identical clocks/voltages. At least that's what I saw after testing dozens of them

Different VID CPU often has different heat output at the same voltage. Often it's lower VID chip runs hotter than higher VID chip, while requiring a little less voltage. There are exceptions, as always...but that's the general trend.

Compare the VID at 3.4 ghz (stock) on your old chip (if you even remember the VID) and the one you're using now. I bet you the VID is going to be lower on your hotter chip.

(The VID is what the BIOS reports as the default "Auto" voltage, and that is the voltage that is used for offsets, and is not the same as the current voltage being reported in health monitoring, which is affected by vdroop or LLC).
