Hello, my pc is acting very strange over the last month. After I left it unused for about 3 months (unplugged), now the CPU just keeps getting hotter after every boot. By that i mean the average temp between each boot is higher than the last. Everything was running at stock settings (optimized default).
Sorry for my bad english but i will try to explain this the best i can:
+When first turned on (after 3 months), temp was at around 36C idle and mid 60s when in load.
+ 2nd boot: 38c at idle and high 60s in load.
+ 3rd boot: 40c at idle and 70c in load.

I figured its a bit hot.
At first i tried to update the bios (from 1701 to 3301) then Clear CMOS, load optimized default. Nothing changed.

So i decided to do a clean up that havent been done since Fall 2015.I reapplied thermal paste (coolaboratory liquid ultra), clean off all the dust on fans and radiators. Now notice how the temps change again.
+ 4th boot (after clean up): temps at 30c idle and never past 53 in load. I was very happy.
+ 5th boot: 33c at idle, 56 in load.
+ 6th boot: 37c at idle, low 60s in load.
+ 7th boot: 38c at idle, mid 60s in load.
+ 8th boot: with just 1 google chrome tab, RealTemp 3.7 software on screen, im seeing 44C. It never reach 40 like this when i first bought it in Fall 2015. Im pretty sure it will reach high 60s to low 70s when in load this time. By "in load" i mean when playing Battlefield 4 after 30mins. Fans curves remain the same for every boot. CPU cooler's pump speed is always at max (3100 rpm, reading from Corsair Link).
Here is how its getting weirder:
"+++": Turn off pc --> Turn off PSU's power switch --> Unplug power cable --> pushed the power button on the case and on the motherboard a few times --> turn it on again after 1-3 hrs. Now temps are back to 30c when idle and 53 in load. After that, cpu's temp just keeps getting hotter after each boot like before. And temps are always back to 30 idle when i try to do the "+++" method.
So in conclusion, if i dont unplug and push the power buttons on the mobo and on the case before i turn the pc on again, cpu's temp will keep getting higher. Im very frustrated about what i should try next.
Core voltage remains stable at 0.744V-0.948-0.978V.
Even though everything is at stock settings, i've noticed that my CPU only reach 3298 Mhz but not 3498 Mhz when playing BF4. I see the core speed 3498 Mhz number pop up in a blink of an eye very rarely on RealTemp software. But it never get to and stay stable at 3498 Mhz when gaming.
I'm suspecting the motherboard since i've heard this board have had all kind of issues since release. However, in my case, this is the first problem i have with it since when i bought it. Im a noob at custom pc, I tried to turn on XMP profile for the 3000 MHz ram once. Windows 7 64bit booted up like normal. temps were a bit hotter (didnt run any test, only surfing webs for a while then i restore it to stock settings).
Below are screen capture showing stats by the time im typing this.
Please help!!
Any advise on how to fix this problem would be very appreciated.
Thank you very much.


My spec is:
CPU i7 5960x
Mobo: Asus Rampage V Extreme (bios 3301)
RAM: 16gb (4x4) 3000MHz Gskill ripjaws 4 series (2133MHz at stock settings)
CPU cooler: Corsair H110i GTX
GPU: 2xEVGA Titan X Hybrid (Maxwell)
PSU: EVGA super nova 1600 P2
Windows 7 Ultimate 64bit

Okay corsair link can be a funny software so if you can try plugging The pump and the two fans directly into the motherboard and control the fans through the Bois. This might keep them stable and stop your temps from changing everytime you boot maybe.

Thanks for the reply.
All my fans are running normally. Im sure i didnt apply too much thermal paste because the thermal paste tube only contain enough for one use (coolaboratory liquid ultra). Im pretty sure the problem is not from the thermal paste. On last boot, my CPU temp was 70 after 30 mins of playing BF4. Then i turned pc off, unpluged and pushed power button a few times to release any remaining power on the mobo. Then let it rest for 3hrs. Turned on again, now my temps are 27c at idle and it never reach 50 after playing BF4 for straight 4hrs. I dont think thermal compound settling can improve my temp that much (20C). As i mentioned on the first post, if i dont unplug the PSU after turning off the pc, my CPU will get hotter on next boot. So im thinking something must be storing inside the cpu or the cpu socket if i dont unplug the PSU. Something is acting like a capacitor maybe?
