Heya guys, If I wanted to Air cool my 790i's NB and mosfets, whats the best way to go?

Alwready have an Enzotech SLF-1 for the SB which works great, but unsure about the NB and mosfets.

Thermalright has a Mosfet cooler for the board, but only works on the I/O side, their supposedly working on a fix to make it work on the top also (was origonally supposed to be and marketed as a soloution for both, but they messed up on the bracket desighn and only works on 1)

I Also have ViperJohns mosfet sinks, but unsure if they will be enough:

Then there is always the Enzotech individual mosfet sinks that you place on each individual mosfet chip with the includded thermal tape:

Wonder which is better to use, and if the would be enough (or better/worse then stock with heatpipe)


Lastly is the NB, best seems to be Thermalright again, and they have 2 options that fit this board, the

Thermalright HR-05 IFX/SLI High-Riser Northbridge Cooler:

Anyone have any experience with either? Do any have better compatibility with the board without running into any issues with the video card or ram?


Thanks for any advice guys.

For whole MOBO I use the Thermalright series, HR-05 IFX SLI for NB , HR-05 IFX for SB and THermalrights for both sets of mosfets, series 2 , on their page there is a compatability list, which board should use which sinks. Those Enzotechs look funny tbh. I'd go for the thermalright series imho.

You sure you didn't reverse the NB and the SB? The SB chip is partly under the first vid card, I thought that would benifit from the offset SLI heatsink. How does the SLIoffset one fit for the NB? Better then a non offset one?

Thanks man

So what do you guys think is best for the mosfets, the Viper Johns or the individual Enzotech's with the thermal tape?
