Do you know what happens when a CPU heatsink is removed? Basically, your CPU that’s been designed to work with a heatsink (so it can achieve higher clock rates than without), will probably overheat and if you do it too much, it can potentially brick your CPU.
How to Under-Clock Your CPU to run without a Heatsink!
Of course, there’s ways around it, by using a software to “under-clock” your CPU. I have used this method on my older laptops where CPU overheating is a problem.
For more on under-clocking, read up on my blog post, “How to control your CPU speeds!” By the way, the free software will also work on desktop computers so, it IS possible to run a computer without a CPU heatsink, it’s just that you need to “under-clock” the CPU.
When you under-clock your CPU, the CPU temperatures can never get so high, in essence, your CPU will run fine but at maybe 50% of its normal speeds.
