Never heard that before but sounds like you know what you're talking about.
When I started OC'ing I was concerned about heat so gave it some thought and decided the easy solution was to leave the side off my case. I know, it's funky but I'm an OldBird senior citizen and not out to impress anyone.
Was crusing WallyWorld and saw a small $5.00 fan on the close out rack so got it and sat it pointing inside the open case and everything runs nice and cool, and very quiet to. Aero7 cooling the CPU HS and the small fan and that's all, so quiet you can barely heard it and I like quiet.
Before with the side on I had one 80mm 32CFM intake and exaust and the EverCool CUD-725 cooler and that puppy was way to loud for me. Using a 350W Fortron with the auto fan speed control and now it never goes in high gear so PSU fan noise not a problem.
Have an EPOX in a full tower case and I found with the side on taking all the strip brackets off the back and pointing the fan toward the bracket holes it runs mch cooler and quiet. Same thing works for the mid tower case but I prefer leaving the side off.
I'm a clean freak and about once a month I brush out what little dust accumilates so not a big concern there. 'Reckon it boils down to there's a lot of ways to skin a Rabbit and what works for the individual user. With the funky yet efficent set up I have I don't think hot capicators or hot anything will be a problem.
I guess I have a different way of looking at what something costs, but considering I paid about $100. for the 8RGA+, if it lasts five years I figure it cost me twenty bucks a year or about two bucks a month, so I got my moneys worth and it's a throw away. The 8RGA I got refurb for $51.00 and I call that dirt cheap.
I guarantee I will never buy a new MB again because the refurbs are so much cheaper. Since I have three 'puters (two Epox, one Soltek) I use one for about a month at the time so doubt I'll have to replace one anytime soon. What do I need with three? Don't know other than I refuse to grow up and I need lot's of toys to play with.
(How many 63 year old Dudes you see building their own listening to Jimi Hendrix and OC'ing ? ? ?)
Ya'll have yourself a fine week end and always good exchanging thoughts and ideas with you. O C
