Exordus

I have a stock Corsair 5185. I’ve only noticed the issue while playing games, although my wife said it did start up once while idle. https://www.corsair.com/us/en/Categories/Products/Systems/Vengeance-PC/CORSAIR-VENGEANCE-GAMING-PC/p/CS-9030002-NA

I have a 2 year old Vengeance that I absolutely love. One of the reasons I like it is because of how quiet it is. Recently my fans seem to kick into overdrive and make noise when playing demanding video games. Can anyone tell me what might cause this?

I was going to pull the trigger on the 5180 since it was so well priced now, then decided to go one step higher and get the 5185. Problem is, I can only order the 5180 on the Corsair website, the 5185 isn't available? It wants to send me to Amazon.com, which I wouldn't mind if I got it for the listed price on the Corsair website. Also....does the customer support line always have you wait, well, over 20 minutes now and counting? Thank you, Eager for a new computer EDIT: finally got through to customer support. thank you anyway
