A CPU cooler protects your CPU from thermal throttling, stability points, and heat-related harm.Put merely: It’s a significant {hardware} element that unleashes your CPU’s full potential.Nevertheless, there are occasions when you might have to take away the CPU cooler, whether or not due to a troubleshooting step or upgrading the cooler itself.In concept, this seems like a easy process. You turn off your gadget, wriggle the cooler backwards and forwards, and gently pry it off. Viola.However… what occurs when your CPU cooler is so decided to guard your CPU from hurt, that it refuses to return off, regardless of how a lot you pry and take a look at?Thermal paste, the sticky substance that’s utilized between the CPU cooler and the processor, is the possible wrongdoer.Its important job is to reduce the microscopic air gaps between the 2 surfaces — one thing which might considerably enhance thermal conductivity and hold temperatures low. However in sure conditions, it may trigger the CPU cooler and CPU to get caught or “glued” collectively.On this article, we’ll share just a few strategies that’ll enable you to safely take away a caught CPU cooler. We’ll additionally delve somewhat extra into what precisely thermal paste is and the right way to reapply it.What Is the Function of Thermal Paste?A Central Processing Unit (CPU) generates a complete load of warmth and may attain scorching temperatures (as much as 100 levels Celsius), particularly if it’s put beneath heavy load.If this warmth is left unchecked, it may result in thermal throttling and trigger your PC to stutter, decelerate, freeze, or shut down solely. It will probably even end in everlasting {hardware} harm if continued for prolonged intervals.So, nothing enjoyable.That’s the place a CPU cooler is available in (cue superhero music). It makes use of followers or a liquid coolant to maintain temperatures low, guaranteeing your processor won’t ever attain the “hazard zone” and be put susceptible to all of the dangerous stuff.Nevertheless, for the CPU cooler to be efficient, it must be completely connected to the processor’s built-in warmth spreader (IHS) — one thing that’s not precisely possible due to the tiny, air-trapping imperfections that naturally happen on the IHS and CPU cooler plate surfaces.Thermal paste is the substance that makes this excellent attachment doable. It spreads onto these surfaces and “plugs up” all their imperfections.When correctly utilized, and with a high-quality cooler in place, CPU temperatures normally keep under 70 to 80 levels Celsius.Why is My CPU Cooler Glued to the CPU?Thermal paste begins as a mushy, greasy substance. Nevertheless, over time because the thermal paste is uncovered to quite a few heating/cooling cycles, it may dry up and harden, leading to a “cement-like” grip that glues your CPU cooler to the CPU.Most thermal pastes can final for a number of years earlier than they dry up and trigger noticeable points, however there are some cases the place it may occur so much earlier, together with:
You’re utilizing a low-quality thermal paste
The thermal paste wasn’t utilized correctly
You used an outdated thermal paste product that was poorly saved or previous its shelf life
Extreme publicity to warmth (i.e. placing your PC beneath heavy load continuously)A excessive CPU temperature is the primary crimson flag that the thermal paste is drying up and shedding its warmth switch effectivity. It will usually be adopted by efficiency points.Dried-up thermal paste can even seem crumbly, onerous, and flaky in texture.The best way to Get a CPU Cooler Off of a CPU: A Shut LookWe’ll begin with the most secure and most typical strategies to get a CPU cooler off of a CPU.As soon as we’ve lined the fundamentals, we’ll then introduce some much less “typical” strategies — these are typically protected so long as you’re extraordinarily cautious and assured round {hardware}.As at all times, we advocate taking your PC to an skilled for those who’re not a hardware-savvy particular person.1.

Guarantee every part is switched off from the ability and any cables are disconnected
Set the warmth gun or hair dryer at low-to-medium warmth and maintain it just a few inches away from the CPU cooler
Apply the warmth for just a few seconds, rotating across the CPU cooler. Then, verify if the thermal paste has loosened
When you nonetheless can’t take away the cooler, repeat this course of just a few extra timesIf heating the thermal paste immediately doesn’t work, you’ll subsequent wish to swap out your hair dryer for some dental floss (yep, we’re being resourceful at this time).5. Pry with Dental Floss and Isopropyl AlcoholYes. Dental floss — or one other thread-like materials — is probably going going to be your savior if warmth isn’t working its typical magic.That is particularly the case for those who’ve managed to drag the CPU out of its socket and it’s now caught to the cooler (extra on this shortly).The strategy entails rigorously sliding a chunk of floss in between the cooler plate and IHS to bodily break the thermal paste’s seal.Right here’s the right way to go concerning the course of. Once more, guarantee every part is switched off earlier than trying this:
Dampen a cotton swab with a 90% isopropyl alcohol answer
Gently dab it across the edges of the IHS, ensuring to not get it anyplace else
Rigorously slide a chunk of dental floss beneath, in between the cooler and CPU. It’s possible you’ll have to barely wriggle it backwards and forwards for those who really feel some rigidity (however hold to gentle strain)
The adhesive bond will normally break as you slide the dental floss throughout, particularly if you hit the center. It’s possible you’ll have to work on it from every nook if it’s significantly cussedWhen you don’t have dental floss or sturdy thread readily available, you should utilize a enterprise card as a substitute.This ultimate methodology ought to resolve the issue, however attain out to knowledgeable for assist in case your CPU and the cooler stay glued collectively.CPU Got here Out of Socket: Are Bent CPU Pins Salvageable?Proper.
