TL;DR - Skip first 3 paragraphs Today I decided to open up my Blade (being that the warranty has expired since I purchased in July 2015), to clean it up. The reason for wanting to clean my machine is that I noticed the fans instantly ramping up to 100% as soon as I would open the lid from sleep or hibernate. As well as CPU and DISK always bouncing from 0 - 80 under normal load. I understand that cleaning the fans may not have fixed this, but in my particular case, it did. So I was curious as to why this was happening. Prior to opening up the Blade, I did some research to see what other fellow Bladeians were posting about their thermal issues and the causes of such. I decided to dive head removing the rear panel, and the first thing I noticed were my glorious heat sinks, and the massive clump of lint in each side (pics). This is the first time in 2 years this [2015 Razer Blade] back panel has ever been removed, and I've sprayed air in the fans and exhaust ports before [with minimal effect] every couple months. Upon installation of the rear panel and starting up the machine, something weird happened. No insta-fan cyclone. I opened the back panel back up to check that all wires were connected and everything checked out. I even went as far as to try to put load on the Blade by running 12 tabs of Youtube for 6 minutes [6 in Edge, 6 in Chrome all playing videos] to get the fans spinning. Yes I am aware that this wasn't the best test, but astonishingly enough... no mega cyclone on my table. Of course I am aware that leaving those open for longer would've surely made the fans spin wild, but prior to the lint removal, they would have spun up instantly. _______________________________________________________________________________ Compressed air can only remove so much. Opening your machine and removing debris will surely help stay cooler and quieter under normal load, as it did in my case. ***Be way of your warranty, as I believe just removing the back panel will void warranty*** But my reason for posting is I was wondering about the design of the thermals. Why is it a solid piece of copper, rather than a copper tube with a narrow cavity with holes on either end to dissipate heat faster and move more air? And would it make any difference installing the new 2017 Blade fans on my 2015 Blade, or are they the same. (I am already over the fact that the way the heat sinks are attached are pretty lame) Bonus question: is there anyway to get chroma lighting on my 2015 Blade. I am not afraid of doing surgery.
