This isn't exactly a PC build, but maybe I can get some recommendations for places (ideally in the south, I'm in Berks). What I've got is a ventilation kit for my car, which was made by Webasto for BMW. It's an array of 6 IP44-rated axial fans, a voltage converter (the thing is powered by a solar panel), supercapacitors and a controller board. Can anyone recommend a place that would be able to upgrade some of these bits, eg the fans, capacitors? I am thinking there are efficiency gains to be had, and maybe some new tech, eg a fan with a built in temp sensor. Thought PC-build places might help, but they all seem to be either very specialised (the consumer ones) or focused on the commercial/industrial market (likely won't take on a one off). cheers
