Guys

I just got my new 920 today after 2 faulty corsair h100's in a row. I hooked it up outside my chassis to ensure its functional before installing it completely. The pump appears to be working and the unit lights up as it should. How loud is the pump supposed to be? Mine has a light/gentle purr to it, I assume this is normal? How loud should it be? Almost inaudible or slightly audible?

I absolutely can't hear the pump (at 100%) over the fans (at 600rpm), if that tells you anything.

make sure to lean your computer to where the radiator is higher than the pump for a few mins, as these things do leave room for expansion of the liquid. if it's really loud, TURN IT OFF and do this. This is Especially bad if you have mounted the radiator inlet/outlet tubes lower than the inlet/outlet Tubes of the pump.

You may be right. As I said I hooked it up outside my PC without completely installing the unit (did not want to go through all the trouble and have a 3rd repeat to remove a faulty unit - like my 1st and 2nd Corsair H100's).

Since it was outside the chassis, the pump/waterblock and the radiator were at the same height level (due to being put on the floor).

To inspect how loud the unit is and to see if it is normal, I have lifted the pump/waterblock up slightly higher that the radiator still stationary on the floor to bring it closer to my ear while bent down on my knees. This may be exactly what you were explaining to me (positioning).

Look, I won't say its VERY loud, just a light/gentle purr to it - just wanted to confirm if this is normal so I can install the unit completely.

What I will do is try what you suggested and see if I can take a video or audio clip and post it here tonight when I get home so you guys can be the judges of it?

These things do make SOME noise, but not as much as the fans. The little bit of noise they do make, will be completely gone in a closed case. I mean, any pump that spins 3000RPMs is going to make noise. But TBH, isn't it WAY quieter than installing a HS with 120MM fans or larger? I think the noise your hearing is probably normal, if you have to get on your hands and knees to hear it

also, for reference, since there is a small pocket of air in these systems, I would not suggest mounting the intake/outlet tubes of the radiator on top, I'd mount them toward the bottom simply because if there is air in the pump, it will bubble up into the radiator, whereas on top, it will continue to suck air. Personally, if I had a little more head-room above my motherboard in my case, I woul mount it on the top exhaust fan slot, just think that would be so much better.

Makes sense. I will give it a bash tonight when I get home and report back with some findings. Thanks

I didn't know about the air pocket thing. I assumed they were pretty well setup from the factory, or that the bubbles would work themselves out as they were circulated through the system.

I r/r the pump last night before settling in to play BF3. While it was off I cleaned and reapplied TIM very carefully. It seems to have made a significant difference, putting me inline with the TT Big Typhoon temps, although it is louder for the same performance. Still on the fence as of right now.

Then what about waterblock/pump orientation? Any suggestions?

I don't think there is any "sweet spot" in the orientation of the pump. As a matter of fact, about a week ago, a Antec rep chimed in on here and claimed that it should not matter which way you apply your pump. I was in the process of testing a different orientation when my Computer quit, do to what I think was complications with the RAM.

As a Commercial Fisherman, (at one time), I've dealt with many large pump setups, and TBH, straight up and straight down usually cause the most strain on large pumps, simply cause it's hard to keep them primed, or gravity pulling the weight. I was going to try at a semi-top mounted inlet/outlet tube setup, with the tubes just 3 notches Clock-wise from straight up.

Far as these things go, finding that "Sweet spot" for each individual computer is still trial and error, none of which, I think, will put it in harms way.

Hi again. Finaly at home in front of "the other wife" I have again connected the 920 outside the chassis for testing before diving in and installing it completely.

I used a 3-pin fan connector extension cable to hook up the pump so it can reach comfortably outside the chassis. I orientated the radiator that the inlet/outlet pipes are at the bottom (facing downwards toward mother earth). I ensured that the waterblock/pump is situated lower than the radiator as you suggested - still hearing the light purr (almost like a fishtank pump). I played with different orientations for the waterblock while still ensuring it is slighly lower than the rad - same results?

Somewhere I read that the 3-pin motherboard fan header can push out lower voltage due to the motherboard BIOS setting. To investigate if this was the case I used a molex to 3-pin fan adapter to ensure the pump get a full 12 volts. Thereafter I started up the unit - again same light purr noise from the pump.

I tried fiddling a little bymoving the rad and/or waterblock/pump units - same results.

I will edit this post in a couple of minuted to include a video upload to illustrate the sound coming from the unit
