CPU Temperatures Fluctuations i7-4790k

[kushalakachin2]

My CPU temperatures fluctuate a lot !
PC also reboots very randomly without any warnings.
Would reboot at idle as well.
Tried reinstalling drivers with cleaning of registry, formatted the OS but it remained the same.
Upon monitoring I found out the temps are fluctuating from 35-99° !!!
I have not overclocked !
I have no idea what's going wrong.
I reinstalled the CPU cooler with new thermal compound and ran prime95.
The moment it started running the CPU temps touched 99, I stopped the process immediately.

My rig:
Intel i7 4790k processor (4ghz - turbo - 4.4ghz)
Gigabyte GA-Z97M-D3H LGA1150
Zotac Nvidia GTX 750Ti 2gb Ddr5
WD Caviar Green 2TB (WD20EZRX)
Transcend DDR3 1333 4gb pc dram (JM1333KLN-4G) X 2
Corsair VS650 650 Watt PSu
Circle Gaming Cabinet with 3 Fans (2 in- 3 out)

Yes its spinning properly, I've had this rig since a year now. The cooler has been performing well.
You think a new cooler would help ?

I'm thinking that the cooler is not properly set. Maybe some plastic broke? You should recheck it.

Hey bro,
I checked the fans, and theyre working properly. I also set the fan speeds to maximum and yet there was no difference.
But i just discovered while using HWinfo that one of my drive is failing. This the main drive in which my os and most of my data is located.
