Play at your own risk! This is just what I have found so far: TL;DR Notes: RTX heatsink WILL NOT work with 10XX series GPUs Most effective: Rearrange/replace GPU thermal pads for better contact 17 blade fans Good thermal paste Can help: CPU delid + Liquid metal between IHS and die BartX 4.3mm IHS GPU Liquid Metal Questionable: P775X separate GPU/GPU heatsinks, potentially poor contact on CPU/GPU die Hey everyone, I just got myself a P750DM2 and was wondering what kind of cooling mods people have been doing. Here is a little of what I have been doing. First was delidding the 7700k adding some liquid metal and doing the paperclip/toothpick mod: (for me there was no real difference with the paperclip/toothpick mod, but the delid + LM did make a difference) First a comparison between the stock P750DM2 heatsink and the P750TM heat sink that supports the RTX graphics cards. I was curious as to the differences since it should just be easily replaceable. I was able to pick it up for ~$110 shipped so it wasn't expensive at all. Stock P750DM2 P/N: 6-31-P750D3-302 P75XTM RTX GPU P/N: 6-31-P75F3-204 The one on the left is the RTX heatsink. What kind of differences do you guys see? Any benefits? Now the fun part. Some people like the unified heat sink, some don't. I understand in theory they can help each other when one is loaded more than the other, but what if you want to run like a 8700k + or 9700k+ with a 1080+ and both create a lot of heat, it might be easier to tune the GPU/CPU for a separate heatsinks. When I got my 1080GTX from MrMogwai he included the CPU and GPU heatsink from a P775TM1!! These are the separate heatsinks for CPU GPU. P775TM1 CPU P/N: 6-31-P77FN-101 GPU P/N: 6-31-P77FN-201 Comparison: The CPU heatsink had to be bent to fit, the P750DM2 comes stock with this bend. The GPU heatsink is also a little longer. In this view you can see the crink/bend on the CPU side to fit, you also see much larger the surface area is of the fins area to dissipate heat! The heatsink pipes are also thicker! Of course this means I had to cut the plastic bits out of the back panel. I only needed to cut the backing panel, not the chassis itself, so if I wanted to go back to the normal heatsink and have it look clean again it is easy to just buy that back panel we remove to access the CPU/GPU. P775TM1 Heatsinks installed: How it sticks out - I want to clean it up to be nicer at a later date. It works well for now. Now I just need to be careful if I move it to not dent the fins and create blockage in the airflow. It still is mobile though and since it is the rear of the laptop I don't ever see it anyways. Curious what you all think and if anyone is doing other things to help keep temps in check. The next thing I want to do is switch out the fans. Apparently there are 17 bladed fans vs normally 14 blade fans? Helps increase airflow that way too?
