What are your idle CPU temperatures on MacBook Pro 15" Retina Display?

I am having problems with my i7 2.4 GHz MacBook Pro 15"(A1398). It is idling around 90C-102C degrees. I recently applied a good-quality thermal paste(Thermal Grizzly Kryonaut), The Inside of the fans, heatsink grills, and the inside of the computer are spotlessly clean but I am still getting those thermal figures. I just ordered a new heatsink for the device but I am not sure what should be the idling temp of this device. Has anyone replaced the heatsink and solved this problem before?

bad heatsink is often the cause for higher temp on these machines. it is usually easy to spot with finger - it should be evenly hot on CPU and wings area. normal idling temp is around 50C but it is only if heatsink is working.

heatink has liquid coolant inside, if it gets out, thats just copper tube.

Thank you for your reply, I will be replacing the heatsink and posting my result over here. I hope the replacement of the heatsink will solve my problem. Btw I installed Sonoma with OCLP but I don't think it will cause that much heat difference in the CPU

After nearly 40days my new/used heatsink arrived from aliexpress and now I am currently writing from the same computer with an idle temp of 52 degrees. If you are having problems with heat change your heatsink. Heatsink change solved my problem. Thank you all for replying. @inwerp @falcon16

Yeah, they can deteriorate over time and lose their cooling ability. Great to see that it fixed your problem. I am not sure how long an aliexpress heatsink would last tho... Well, it did the job!
