Davet58 Posted March 20, 2011 Share Posted March 20, 2011 Where can I find info on the power draw for the H70 pump and fans? The reason I am asking is the CPU fan header on new motherboard is limited to 1A or 12w Link to comment Share on other sites More sharing options...
Danchyk Posted March 21, 2011 Share Posted March 21, 2011 The H70 power draw is negligable (even with a second fan in a push-pull configuration). I don't know the exact number but the pump uses no more power than a standard case fan. I don't think I'd worry about it. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 21, 2011 Corsair Employee Share Posted March 21, 2011 Pump is about 5 watts max, and the fans are about 5 watts max each. Should not be any problems with overloading a header on the board. Link to comment Share on other sites More sharing options...

Captzee Posted February 14, 2012 Share Posted February 14, 2012 Thought I'd renew this thd because the question hasn't been answered and I can't seem to find what the current draw is for the H70 pump. I've used H series coolers on several builds to date and have always connected the fans to either a direct PSU lead or other chassis fan headers because there was no option for fan connections from the pump. This new H70 I bought does have a pigtail connector for the fans and it would be a very clean option to use from a wire management perspective. So what's the current draw for the pump?????? Most MB CPU headers are rated for 1A max. Most 120mm fans will draw right around .45A max. (x 2= .9A) That doesn't leave any headroom (.1A) for the pump. If the pump draws around .2A or .3A I could live with exceeding the CPU header's rating by that much,but if it draws as much(or more) than a fan I can't.

Davet58 Posted February 14, 2012 Author Share Posted February 14, 2012 Connect the pump directly to the power supply and the fans to the cpu header. The pump should really run at full tilt anyways. This is the way I have mine setup on my ********P8P67 mother board with both my cooling fans connected to the PWM connector. Fans draw very little. Ram Guy's answer above pretty much answers the question. Link to comment Share on other sites More sharing options...
Captzee Posted February 14, 2012 Share Posted February 14, 2012 Thanks for the response. I'd rather not connect the pump directly to the PSU. Can't tell if the pump is functioning properly that way. Well,Ram Guy sorta answers the question "about 5 watts"; not very definitive. If you assume 5 watts then current can be calculated to be .416A,close to what a 120mm fan draws. Hummm,that would mean for those people who use these pigtails and connect the pump to the CPU header (as shown in their video) are exceeding their CPU header current by about 50%. Not good. Think I'll just stick with the way I've always hooked these up. Link to comment Share on other sites More sharing options...
parsec Posted February 14, 2012 Share Posted February 14, 2012 You can get molex to three pin adapters that have an extra wire and three pin fan connector that allows you to monitor the fan (or pump) speed. That's what I use on my H60's, so I have the direct PS connection and can see the pump speed too. Link to comment Share on other sites More sharing options...
