H105 push-pull and compatability

Tryzan50 · 17 Mar 2014 at 22:37

Hello,
I have used the H100i in a past build and it was fab. I would like to build another PC and when poking around for new products I found the H105 - an extra thick dual fan aio water cooler from Corsair.
My question is, would there be any significant, real world benefits of using a push pull configuration on this radiator as it is very thick?
And
Would it fit in the 750D with a maximus VI hero in the standard configuration (just two fans) or in a push pull configuration without any modding?

Thanks for any help.

If you have H100i, don't bother getting the h105. If one is not cutting it, the other certainly wont.

They both have similar FPI from pictures (no official fpi figures to be found), which is fairly high as radiators go. Normally i do not recommend push/pull as there is little gain and the money is better spent in buying better quality wcing gear rather than more fans but you see more an advantage to push/pull with AIO coolers like the Corsair units due to their high FPI.

Unfortunately your case has just over 7cm of clearance from the motherboard, which will not allow for the h105 to go there in push/pull. Not a huge loss tbh, decent enough fans will have enough SP to minimize any gain you would have had by going push/pull. You certainly wouldn't gain enough of a temp drop to push for a higher clock. The only practical advantage to push/pull in this scenario is being able to run all the fans at much lower speeds for the same performance, cutting down on noise. You can argue a top end air cooler performs as well and is quieter and cheaper though, if you are in need of a cooler.

The H105 is certainly a small bit better than the H100i. But it does not require push-pull for it, the stock fans are just fine. Push-pull doubles the pressure but not the airflow, and the fans are high pressure fans so doubling up is not needed.

Remember that the H105 does not have the built-in fan controller or the ability to control it via software. You need to physically press the button on the pump to control the fans through it.

Thank you both for you detailed replies, I am going to build another PC so this would not replace my H100i.
It is a shame that a push pull config wouldn't fit but from what you have said it seems like it is a waste of time! I had not thought about the fact that I could not control the cooler like the H100i but if I connect the power to the CPU fan header, as you must, doesn't the motherboard change the speed of the fans and pump according to the temperature of the CPU? Is there any sign of a H105i?
