Ok thanks.
I need the cleaning because dust is building up pretty badly in there. I bought the card when it first came out (I felt like a retard two months later) and I just left the stock compound on there, and havent really kept up on clearing away dust.
I'll be replacing the HS with an NV Silencer 5 (Rev 2) because it's summer time here in California, and my case temps have gone through the roof, and I think exhausting system on the Silencer should help a bit.
