Cooling systems that fit RNDP600E?

I do, read my signature. Last night I was doing a NFS back transfer and everything was pegged. The only thing was that my SYSFan was running ~ 1100 RPM, WAY slower than the stock. My worry came that my SYSTemp was 149*, which was the MAX "normal" range. However, it never went above this. The CPUFan was ~ 700 RPM and CPUTemp never went above 95* :)

Keep in mind that I used ULNA and LNA in my Noctua Fans. I LOVE THEM and fit just fine. No modifications needed at all. The CPU fan though @ 80x80x25mm was a SNUG fit, BUT it will fit. Even doing a NAS to NAS transfer, I could BARELY hear my fans. However, when I peg my CPU with transcodes will be the real test.

Lastly, I inadvertently set my CPUFan backwards (to pull from CPU) rather than to push to CPU. Actually it is cooler, BUT I will fix this when I complete my back ups.

I love the mods I have done on my ReadyNas Pro Pioneer. Although HATE that I cannot bond the NICS, but I am working on that also!

Good luck
