Thinking about making a custom heatsink for my laptop. Can source the heatpipes, copper block, copper shims and fin stacks from eBay for about £30. Need to check out places around here that could CNC the block from provided drawings.
I’ll take it apart tomorrow and take some measurements. Would want to make a full cover block to help VRM cooling, too. Only problem I can see running into would be a good retention mechanism. Probably just be easier to desolder the tiny brackets from the current heatsink, but we’ll see.
I got rid of my desktop setup, and switched over to this laptop about 6 months ago. It’s great for everything I need it to do, and the CPU is about twice as powerful as my overclocked 4960K was, but I’m not happy with the temperatures it runs at whilst under load.
I’m running it with a -135mV offset on the cache and core. Rendering, it hits above 95°C on a couple of cores straight away (no matter how many times it’s repasted). Loading both the GPU and CPU results in it thermal throttling, which means that the FPS tanks in 3D viewports, or games.
The aim of the new block is to add more thermal mass, making it take longer for the heatsink to heat up/cool down, and therefore give the fans a longer amount of time to ramp up and down; cover the VRM, to stop power limit throttling; and even out the temperature delta between cores, which is currently more than 10°C at load.
