If the fans are not working properly, then that would definitely explain the temperature increasing that rapidly. There could also be other factors. I would recommend checking all vents to make sure that no dust or debris is clogging, and check using a monitoring program such as speedfan or, as I prefer to use, HWiNFO64 to manage fan speeds or at least check what speed they are at. These programs are helpful even just as monitoring software.

Hi,

To check it whether the temperature increasing happened in hard disk or motherboard?

If HDD will be overheating, Try this software to monitor your heat temperature namely "Hard Disk Sentinel".

Here the link to download that software below,

Let me know, what temperature show in your computer. 

Hi,
Did you find the solution for this? I'm facing the same problem. I did couple of test by different software. All results indicate to the disable of the fan on the GPU. The fan speed on my GPU stays at 12rmp which is a very very low speed. No matter what I do to adjust the speed by using software, it just doesnt work. It must be the hardware problems.

my issue being the GPU fan only running at 11RPM, seems to be set that way and wont change even with speedfan.

Hi,
Did you find the solution for this? I'm facing the same problem.
exact same issue need help ASAP

Well, thanks for you reply. But I figured out the problem by myself.

I opened up the computer and took off the GPU (R9 370). I was turning the fan by my finger and realized that the fan is too big for the round opening[8o|]. When the fan moves it scrubs the GPU box. I really didn't want to send the machine back and wait another month. So I used a little knife, cut the opening a bit bigger.  After that the GPU works perfectly. No overheating probem anymore and the fan speed looks normal. 

I am sorry this is a little late. Ive been unavailable for a while preoccupied with many other things. Here is the link

As an additional note, keep in mind that many "overheating" resolutions are based around airflow. In most cvases, cleaning out vents and dust are the key points. However, if the fan is simply not speeding up past the 11/12rpm, there may be hardware issues as play.

It s important to do the basics. Check vents, make sure all power cabling is connected properly, open the case and try to power the system to check the fans manually and see if there is something holding back the fan speed physically. Software can sometimes give odd readings with fan speeds, and if its saying 11/12 rpm, then fans may not be spinning at all, or they may be spinning, but the system may not be registering the right speeds, which can lead to the fans not kicking in or speeding up when needed. 

If everything seems fine, then I would encourage calling in to support. Fans not running at all or overworking themselves is a bit different than the fans being stuck at such low rpms. 

Well, there ya go. The fan speed was being physically held back. Glad you found a solution that worked.
