Noctua

So I feel like I should be giving this a five star to rave about a site and a company I love just because of them having a response to an inquiry I had that caused me to just fall in love with the way they work! I haven't yet ordered from them (But I plan to if this works out!). So i have an old Thermaltake Armor Revo VO200M6W2N Snow Edition SECC ATX Full Tower Computer Case that's got a fan on the side of the case that's always made a clicking noise and clipped against the metal grate on the case. That fan is finally failing and needs replaced. I decided I would like to order a new Noctua NF-A20 PWM, 4-Pin Premium Quiet Fan (200mm, Brown) to replace the old fan. The issue I found is that the Noctua fan does not have any compatibility reviews for my particular case, and apparently there's really no standard configuration between computer parts companies for the 200mm fans as far as how they mount on a case (and of course dimensions and space in the case make a difference too) I need to replace the one on my case and I don't want to replace it with the fan that's already failed. I looked into two other companies that have the size fan I wanted and reviews for the other companies stated they were better off going with Noctua fans. As my case wasn't listed I contacted the company to check if they had anything on my case. Instead of providing information they sent an email offering to send me one free of charge so I can give them the information on if it's compatible and give them the review for their fan with my case. I haven't even ordered yet and I'm excited to find if I get the fan, and to be able to provide them the information on if the fan is actually compatible or if it is one that won't fit the case.
