Is there any product like the Corsair H80/H100 that's radiator fits into an 80mm fan slot. I don't need anything for overclocking, just thought it might be cool and save some room on the motherboard pcb
YEP!
i was searching for this a while back, and found a dual 80mm rad, then i stumbled across this while searching today. http://www.frozencpu.com/ex-rad-30.html
its a black ice rad super small. not sure if you can change those fittings though, guess its barbs only? check it out
you would get roughly the cooling abilities of a h50 out of these thick 80mm rads. they make dual 80mm as well, i remember using 2 of the dual 80mm in the old chieftec dragon cases back in the days as well as the lian-li pc-60 series
in the modern day of time, these would be great for i3 chips and the low power i5 s series.
add these plus a apogee drive II and you would have a nice SFF setup thats easy and convenient.
or you can also just get 80mm to 120mm adapters to mount h40/h50
