FREQUENTLY ASKED QUESTIONS ABOUT THERMAL PASTES
Thermal Paste – A silvery-gray substance that you apply to a processor before installing a cooling solution. It allows for an efficient transfer of heat from the IHS of the processor to the base plate or water block of the CPU cooler that is designed to dissipate that heat.
Thermal paste, or some oily thermal interface material, is necessary because it fills in the microscopic imperfections that otherwise trap air particles between the CPU and the heatsink, preventing the CPU from properly cooling.
Not using thermal paste between the CPU and the heat sink will cause it to eventually overheat and fail. This may not happen straight away but it will happen and in a much shorter time than if you use the thermal paste.
Emphasis on should. We recommend putting some on a metallic surface and spreading to check its consistency and smoothness. If it has separated, comes out clumpy or watery, then throw it away and get yourself a new tube of thermal paste.
Once you remove the heatsink off the CPU, you create a void where the thermal paste used to be. Reapplying the heat sink will not guarantee the entire surface will be equally covered and will have the risk of overheating because of the unprotected areas.
You can use a cooler without thermal paste, but the thermals will be bad, let’s say 10-15 degrees celsius more hot. … The heatsink will still be in contact with the cpu surface without the thermal paste, but it will not be a perfect contact, so the heat transfer will be worse.
Toothpaste is another option that you can use to help cooling but it isn’t ad good as store-bought thermal paste. It is not a long term solution since it dries quickly, will work for a little bit then burn up. It is good for CPUs that do not run very hot.
In fact, replacing the PS4 thermal paste is a sensitive process that needs accuracy, care and concentration. If you don’t apply the thermal paste correctly on the PS4 CPU, you’ll cause more damage to the system. Additionally, in most cases, the PS4 thermal paste has not to do with the heating problems you’re facing.
You probably destroyed the motherboard and cpu when you took off the heatsink/fan. If you don’t take the hs/f with a twisting motion especially with too much thermal paste you’ll yank the cpu out of the socket and leave a pin or two in the socket. So the Mb socket is shot and so is the cpu.
Thermal paste will dry after about 2-3 years of being properly applied to a cpu and heatsink, the heat generated by the cpu/gpu causes this yes.
When it comes to applying thermal paste, less is more: a small, pea-sized drop is all you need. Don’t spread it around, either—the heatsink will spread it out evenly as you screw it in.
