isme Posted August 27, 2015 Share Posted August 27, 2015 I have 4 F3-120(1850 rpm)fans rated voltage 12v dc at 1.44 watt power draw can I run all 4 fans safely from the h100i pump head or do they draw to much power. thanks for all replies Link to comment Share on other sites More sharing options...
wytnyt Posted August 27, 2015 Share Posted August 27, 2015 I believe the hydro handles 2 per for a total of 4 amp so your ok... Link to comment Share on other sites More sharing options...
isme Posted August 27, 2015 Author Share Posted August 27, 2015 thanks for your reply, i cannot find any info in the manual or online do you know where i could find exact specs for this info Link to comment Share on other sites More sharing options...
c-attack Posted August 27, 2015 Share Posted August 27, 2015 Yes, be careful with the original H80i/100i current draws through the pump fan controller. It was a little sensitive and pushing the amperage limit usually had consequences. Link to comment Share on other sites More sharing options...

c-attack Posted August 27, 2015 Share Posted August 27, 2015 If you have two on the block controller and two on the motherboard, you are just fine. F3-120? If my math skills are still intact after lunch, that's 0.12A per fan. That well under the included fans' draw of 0.36A per fan. You're good.

You're good. thats good news and the fans are the new Vardar i have the F3-120(120mm)1850rpm high static pressure and are very quiet and 2 of them are cooler than the 4 stock fans i had in push pull.again thank you for your good news Link to comment Share on other sites More sharing options...
wytnyt Posted August 27, 2015 Share Posted August 27, 2015 thanks for your reply, i cannot find any info in the manual or online do you know where i could find exact specs for this info I just gave them 2a on each header OR a total of 4a total...

isme Posted August 27, 2015 Author Share Posted August 27, 2015 I just gave them 2w on each header OR a total of 4w total...so if each fan is 1.44watts at .12 amps can i keep them on the same fan splitter or do i need to connect the second splitter and run each fan that way?

c-attack Posted August 28, 2015 Share Posted August 28, 2015 4 fans on 1 splitter? The draw should be OK, but I think I would prefer separate control of the two coolers. Are you short headers? Or are you trying to get them all controlled through LINK? Link to comment Share on other sites More sharing options...
wytnyt Posted August 28, 2015 Share Posted August 28, 2015 so if each fan is 1.44watts at .12 amps can i keep them on the same fan splitter or do i need to connect the second splitter and run each fan that way? isme,I revised my earlier post,I put watts and it should have been amperage,sorry for any misleading but as c-attack stated ,your good to go c-attack,please correct me in the future if I mis-post again In my defence Im trying to do a zillion things so I wont hear my grand daughter's mindcraft...:eek: Link to comment Share on other sites More sharing options...

The warranty on my math skills expires in unison with my morning caffeine. Any response made during prime time hours should probably discounted entirely due to the accompanying intelligence drop associated with viewing television at that hour.

Electrically, I think you're fine. How the control will serve you may take some tweaking. Since the H100i runs it fans off the it's water temperature alone, you won't necessarily get the fan speed you want on the GPU in a low-moderate CPU/High GPU load scenario --- like most games. Best bet might be running a fixed fan speed that you can tolerate while under load. You can save it as a preset and then one-click load it up before heavier activity.
