    Anyone knows of anybody who makes custom heatsinks for laptops, because I saw some guy on a forum saying he knew a guy who made custom heatsinks. Also, because of limited space in my laptop, the only way I can add a heatpipe myself is by stacking the heatpipes. Is that a good idea or will it just increase temps?

    it will definitely improve the speed and capacity at which heat is moved away from the CPU/GPU. however, at some point the bottleneck will become the radiator size. so yeah, it will give u better temps but only up to a point.

    Thanks for the reply! Is it possible to upgrade the rad to one with higher density and upgrade the fan too, that way bottlenecking is reduced?

    im sure its possible, but ull have to source the parts and make them physically and electrically compatible with the chassis. also, a lot of finetuning will be involved for proper contact with gpu/cpu...

    Yes fan upgrades have been a thing in the past, since they are the next best thing after checking TIM, pressure, heatsink surface evenness and alignment, and since the fans themselves are sourced from 3rd party manufacturers like Delta, Adda, Forcecon, there may be interchangeable options there. But it depends on the model. A service manual with part numbers and schematics will help to understand what is compatible, 3 pin vs 4 pin, VDC vs PWM speed control, etc. Clevos have hissy fits and auto shutdown if fans aren't detected.

    Stacking heatpipes is less effective than adding them alongside to the heatplate that actually contacts the heat source (parallel is better than serial).

    Fin density is pretty much optimised at about 0.7mm. Smaller than that starts restricting air flow. Adding fin volume from a bigger radiator will help, assuming there's the space to fit it and the airflow through it. Replacing an aluminium rad with copper will help but only meaningfully in a high heat load situation.

    Also the ability to control fans is important too, especially if the control scheme is optimised for noise not temps. Mods may lead to less fans but not budge temps at all.

    I agree with @bennyg you can gain a lot by controlling the fans. My default fan curve was set to only run the fans at 100% past 90C. Not ideal! The GPU would not run 100% fans until 80C; well past the downclocking limit of Turing. For both I was losing out on maximum Boost clock with the default fan profile.

    The CPU now runs 100% fan speed @ 79C which it rarely sees thanks the the new aggressive fan curve which ramps up faster. The GPU now runs 100% fan speed at 65C and with a proper under volt @ .7620v its usually sitting in the low 60C's!

    What do you mean by electrically compatible? Like make sure it doesnt short anything?

    Yea I kinda knew about it being less effective but I have space limitations so thats a problem. Also just to check my terminology, fin density is how thick the fin is, and volume is the number of fins?

    How do you control your fan speeds? I only have 1 fan... and Ive been using notebook fan control but iirc it stops working when Nvidia Optimus kicks in. I think it can be solved with a cracked BIOS but I am not sure how to do that. Does anyone know?

    haha no i was referring to the replacement fans in that regard. be sure that the voltage is identical to what the board connector provides, otherwise ull have too little or too much power going through to the fan, the latter potentially being able to burn it out.

    fin density is kinda both. its the amount of fins ure cramming into a length or volume of space, so its also proportional to the thickness of the fins and the gaps in between.

    Thanks for your help! Also do you know how to mod a InsydeH20 bios?
