A software driver that takes 2.3+ GB to install just to tell you fan speeds and temps, that runs 64+ processes and runs at 6% + CPU usage all of the time is not "impressive" in any universe. And certainly not when that software is riddled with bugs, some as old as 3+ years - Fundamental stuff that should have been fixed by now.
As of 2020 Corsair will not honor warranties if you do not own a cell phone. I've had a cooler and PSU refused simply because I do not own a cell phone. I have a landline. To quote Corsair service "Carriers can only deliver to a cell phone, not to a physical address".
I've never had a carrier here in Australia refuse to deliver something to me because I don't have a cell phone, even the pathetic Australia Post/StarTrack can manage to deliver to a physical address, albeit extremely slowly.
I have 10 PCs. All of them had Corsair coolers and PSUs. Some had Corsair RAM and commander pro's. Of those 10 PCs I had to make 14 cooler replacements over an 3 year period with the coolers failing, typically the pumps.
The coolers are good when they work, but with average 8 month life span, they are not a solid purchase choice. These include the H100, H100 V2, H110, H115 and H150 and variants of them.
Of the few Corsair coolers I have left they are using CorsairLink which takes 45mb, runs 1 process, uses 0.5% CPU on average and does everything I need it to do for a cooler - tell me temps and fan speeds.
