Many users ask on different forums that they are dealing with the massive overheating problems in their desktop PC. Even the modern PC having high advanced hardware installed in it faces the rising temperature problem.
Instant case had the following components:
- Case: Corsair Vengeance C70 ATX
- CPU: i7-6700K (running at stock multiplier)
- CPU cooler: Lepa Aquachanger 240 (liquid cooler)
- MSI Z170A GAMING M7 ATX LGA1151
- Memory: G.SKILL Ripjaws V DDR4 3000 C15 2x16GB
- Boot drive: Samsung 960 Evo NVMe PCIe M.2 500GB
- Power Supply: Corsair RMx 750 W 80+ Gold
- Video card: Nvidia GTX 1070 Founder’s Edition
According to this user, his system showed overheating symptoms. So he did some troubleshooting to solve the rising PC temperature problem. Some of these are as under:
- The liquid cooling fans spin faster right after Windows 10 turn on so the temperature remains above normal limits i.e. 45-50C.
- During idle the CPU temperature goes above 75-95C, that way hot than it should be.
- Ultimately PC gets slower overtime eventually it’s freezing.
- After restarting PC the CPU temps reading still remains high at 75.
- Sometimes a black empty screen showed up after reboot.
- Even the opening of the case to prevent CPU overheating didn’t work.
Once the PC is left off for several minutes and turn on again the CPU temps readings gets normal but not for a long time.
So what is the problem that’s causing this CPU overheating. Well here is a simple solution to fix this problem.
Solution of Rising CPU temperatures in idle
First you need to check that your CPU cooler, most of the time this hardware is the core problem of CPU heating.
If your CPU cooler is old i.e more than 3-4 years then you need to replace it and buy a new one.
Now this may seen odd but it what i have tried to fix CPU cooler. If you take off the cooler and give it a good shake. It might remove air bubble trapped inside or other particle that is blocking the pump.
Add extra stock fans on the front and sides of the case to compensate negative pressure out of your system. To enhance the capabilities of your case to deliver fresh air, you need to install two 120/140mm front intakes.
If you have recently move your system from one place to another then make sure that all the components are correctly seated and nothing is out of the way.
All CPU coolers has large radiator which are attacked with fans. So make sure that dust of removed because when dust build up in radiators it block the functioning of heat dissipation.
We recommend that you should buy Corsair H115i or Noctua NH-D15S CPU coolers. These are quite, more reliable, cheap and their coolant in tube will not leak.
What Determines the Effectiveness of any CPU cooler?
It’s the size of radiator that determines the effectiveness of any air or liquid CPU cooler.
The all in one cooler or anyother normal air cooler of 160mm have the same size of radiator. What make the difference is the capacity of liquid and air to lower heat.
Normally air cooler has tubes in which fluid circulates and it doesn’t need a pump to make airflow. This liquid will absorb heat and fans will cool it.
