I've looked around online and there really aren't any SB chips that will fit this board, it's no surprise people are turning to this option. I have an HR-05 SLI/IFX in my computer parts box, I'm just reluctant to use it as it seems OTT. One item I do wonder about is the RPM on that SLF, does it sound loud? I have a slow speed 80x15mm 2000 RPM fan I could use on my HR-05 SLI/IFX, just toying with the different options, but your board with your SLF and modification looks great. Cheers.
Yes, good here too thanks. Just changed my Thermalright sinks to MST-81's - not an easy thing to do with the board in situ !.

The SLF fan is rated at 28dba at its max speed of 8000rpm, compared to the 6x120mm fans in the case and the 3x40mm fans on the memory mine is inaudible spinning at 4300RPM on the chassis Q control silent setting. You could always set it to between 50-100% speed using the duty setting on one of the 3 optional fan headers for more control. I would recommend this without hesitation or the CNB-S1L if not trying to max out your system - I have to run my S/B at 1.6v.
