I've built my system around 11 months ago.
I've been using it ever since for 2h/day on average.
I have a CM 690 II advanced and HX750 psu.
I haven't cleaned my case and psu since I built my PC - there is a bit of dust. The front dust filter is dusty and there's some dust inside the case and in the PSU.
What I'm asking is, Can I wait for a month or two before I clean it and blow the dust out? I have to wait for my bro to come over from the other side of the world to help me reassemble the pieces and stuff (he's a pro!).
P.S. my GPU and CPU idle/load temps are pretty cool (temps haven't changed since I built it)
