Initially the PC operated smoothly without the glass cover and fans, everything functioning well. The CPU model was i74770 with a base clock of 3.4 GHz and boost up to 3.9 GHz. The CPU fan used was ARCTIC Alpine 11GT. The power supply came from Corsair CV650. RAM was an 8GB Kingston unit, paired with an Asrock VG4 H81M module. The chassis fans were three intake, three exhaust, two top and one back, all equipped with RGB lighting at 5V3 pin configuration. I recently replaced the fans, but they are controlled remotely and can't be adjusted via Mobo except during GPU stress tests. During benchmarking, the system ran smoothly with a passmark of 87C, then shut down after power management changes. Cooling was switched to passive mode, eliminating any overheating issues. Performance tests showed no shutdowns during Cinebench 3rd or OCCT runs, and temperatures stayed within safe limits.
Here, the issue is clear. Not the thermal paste—thermal paste is mostly thermal paste. Your cooler is designed for 60W of TDP, while your CPU handles 84W. That’s a significant gap. You’ll need a far superior cooling solution. If it fits in your case, the Vetroo V5 or the 224-XT coolers are reasonably affordable (around $30) and offer much better performance. In the short term, if the system isn’t overheating when panels are removed, you can try removing it again. Continuing this pattern will likely cause crashes due to poor thermal management.
Thermal paste can only slightly influence temperatures, typically by about one degree Celsius at most. If things heat up significantly after installing it, it’s likely the cooler isn’t tight enough or is too loose. In your situation, the mounting pressure seems adequate. Even though 4770 isn’t an unlocked CPU, or perhaps because of that, the processor generates more heat than the small cooler can manage. Until you upgrade to a better cooler, consider adding a 120-140 mm fan directly on top of the cooler, directing air downward. The fan on the Arctic cooler may not push enough air through its fins to effectively transfer heat out. * A 4770 unlocked model would generally be considered more efficient, needing less voltage and power for the same speed, whereas non-unlocked versions might be inefficient or limited in overclocking potential.
Turned off the OC that had been active for two years; PC stopped working in 2 seconds after the OCCT power test began.
Your CPU isn't throttling because it's managing heat effectively, allowing stable performance without immediate shutdown.
It might be related to BIOS configurations or hardware adjustments. You should consider upgrading your cooling solution.
