I5 4460 overheating

I have a system with an i5 4460 cpu with a gb b85 mobo. Of late it had been hitting the 90s frequently under load.. So i decided to remove its cooler(a hyper tx3) clean the surface of the cpu and the cooler, reapply the thermal paste and put them back again.


Strangely however, it didn't make any difference and the cpu still hits 90-95 c on load which causes thermal throttling. The cooler is mounted securely and the fan is installed in the proper orientation as well.

Then why does it still over heat like that? Is there some problem with the mobo?

I used some cm mastergel that i received with a cooler last year-is this paste not effectively dissipating the heat from cpu? Will changing it make any difference to the temps? If so, which paste should be used in its place?

Or you could try using a better paste like Thermal Grizzy Kryonaut / Arctic Cooling MX-4 / Shin-Etsu

Cooler master Mastergel, while not bad, is known to be of average performance.

I inspected the motherboard's socket but couldn't spot any damaged or bent pins, this board is only 1 year old-so its really odd that it has started acting this way so soon.

My cpu idles at 38-40 c, but whenever i run some game or use any benchmarking tool like cinebench the temp instantly increases to 80-95c within a matter of mins. Sometimes it also causes thermal throttling.

This has never happened before, earlier the temps barely exceeded 60-65c even under load.

Assuming that something is wrong with the board, should I send it for Rma as its still under warranty?Does gigabyte repair/replace boards which exhibit these types of issues?

Does he respond to msgs from unknown people? I have just sent him a msg about this issue.

Given how buggy win 10 has been of late, can it be the reason for cpu overheating?

One thing that i have observed is when the temps reach 85-90 C, i touch the metal part of the hsf of my hyper tx3 and quite surprisingly, it appears absolutely cool.

If the cpu was really heating up so much wouldn't it have caused the hsf to heat up as well?

It should unless heat transfer is not taking place between processor & cooler correctly.

edit: wait for others as I am not sure how hot metal portion of hsf should be as I never tried touching it.

You don't feel any heat when you touch heat sink. It's pretty much same as room temperature. At least that's how it is in my system. Of course, when running all I can touch is outer most part of the heat sink. By the time heat transfer to this part, all the heat likely to be dissipated.

eddie from gigabyte india has replied to my query and has asked me to send the screenshots of the vrm voltages in hwinfo.By vrm voltages,did he mean the voltages produced by the psu on the common rails like 12v,5v,3.3v etc?Or was he refering to the cpu vcore voltage?

he mentioned that it could be caused by poor case ventilation-but i told him that this should not be the case as the cabinet that i use (corsair 400r) is sufficiently ventilated and has adequate airflow-lets hope i can convince him that the mobo is faulty.

Will using a higher priced cooler with better thermal paste bring the temps down under load?

I swapped out the hyper tx3 and installed a h410r cooler but that didn't work out either-temps still got v. high under load.

Even with a cooler like the hyper tx3, i don't think the cpu should have heated up that much in the first place....

hyper tx3 should be enough for such old gen processor so I don't think changing coolers/thermal paste will help.Issue seems to be either something related to mobo or processor itself.

After sending all the screenshots, he has advised me to submit the mobo at gigabyte's service center in kolkata
and share the Rma no with him - he has also asked me to mention that i was referred by him to someone called rakesh who works there.

Hmm . Interesting Case. Any update ? BTW, my guess is either faulty cpu / motherboard sensor or may be the PSU - I know it's too far but who knows. If you have the motherboard and cpu with you do test with a different PSU and perform the test on a open bench.

i have submitted the motherboard at gigabyte's service center-they said acc. to the serial no its out of warranty,and asked me to send them an email to get approval for rma-i did that and was told my rma has been approved.Yesterday i was informed that they checked the board but couldn't find any issues with it.

I guess i will have to carry my cpu and ram with me and check it at the time of taking delivery whether they have fixed it or not.

Did you get it ? Any more update ?
