Alphacool St30 low rpm Fan Speed?

[Revan654]

I can get two Alphacool 240 ST30 to fit perfectly in my case(In Push), I was wondering if I could run them at low RPM speed? Or is it better to run them in Push/pull? Or is it better idea to get bigger Radiator. I can maybe fit one UT60 inside my case.

- I currently have a few Extra EK Vardar f4-120er fans. I can use those for Radiators without spending even more money, unless some other fans would be better suit like eloops. I do plan to run them at lower RPM below 900 RPM or below if possible.

should be fine for low rpm. its a thin low fpi rad after all. run them intaking cold air

All the Alphacool rads tend to have fairly low FPI meant for silence so you shouldn't have any issues running it below 900RPM. The ST30 one have ~15FPI and aren't overly thick so it wouldn't be a problem, I personally have all Alphacool rad (XT45 and UT60) and run them never higher than 700RPM while on load.

This exactly. I have a 420 ST30 and a 280 XT45 running at 700 RPM.

Thanks for the input, One last question. What kind of temps should I expect? I have a i7 5969x at stock currently.

CPU only? uhh probably like mid to high 50s under load overclocked.

I have a two gpu cpu loop and I don't ramp up my fans much at all so my cpu gets pretty toasty while gaming (up to 70C, which is worse than just cpu stress testing).

Are you just planning a CPU loop or one with single CPU and GPU and it would also depend on the hardware. For dual 240mm rads you should be able to do a fair bit of overclocking with CPU and GPU while keeping things relatively cool.

CPU Only for now, Until I get enough money to buy a GPU block. Not sure whats out their for MSI 980Ti 6G edition. Allot of the blocks are for reference only.

I know with one AIO I have I can get close to 30C at idle. Would I be able to get close to that or better with Watercooling?

Check cooling configurator from EKWB for your specific card:

To AIO's you should be able to get better load performance since your essentially having four 120mm rad spaces for a single CPU and GPU.
