Corsair H50-1 Woahs/Concerns/Annoyances

Standard TIM here, reviews were saying it was good and that replacing it with others would only gain 1C if that so didn't see the point in the hassle of changing it personally.
 
My H50 was OK up until a few weeks ago and now I get a clicking sound when my PC starts up. It seems to go away after a few minutes. Temps Idle around 40c on my i7 930 @stock.


Thoughts anyone, should I be worried at all that the pump will fail?


Thanks
 
I decided to email Corsair to see what they said about the humming/buzzing and they suggested RMA'n the unit, but what's the point when the new unit will most likely do the same. Can't hear it when the case side is on so just going live with it
 
Yep my H50 makes a buzzing sound too though I don't notice it anymore. When I first installed it, the noise bugged me somewhat. I tried tapping the pump etc. I have seen a post about moving the H50 rad so hoses moved to different angle, this may change the way the water is moved I guess thus change in buzz?
In the end I connected the pump directly to the PSU so that it runs at max rpm and voltage. You will need an adapter, I used one that came with my Noctua 120mm fan. I think its quieter, still a buzz, but doesnt annoy, hardly notice it.
Very pleased with the H50 much better than a CPU fan ramping up the RPM when playing BC2;)

I have a socket 1156 and was also thinking what the hell fitting the backplane for the H70. Just didn't look right sitting in that position.

I ran with the TIM supplied for two weeks then decided to change it for some MX3. They really did slap on the TIM. Took ages to clean the stuff off. Seemed like they stick way too much on. I'm tempted to buy a tube of the Shin-Etsu and do myself. The temps with MX3 seem very slightly less. I went with the line and not pea method.
 
FYI ... I put the pump on a 3pin connector fed from a molex direct off of the PSU so it was getting a full 12v and the humming/buzzing has stopped. Admittidley I can't monitor the pump's rpm like that but the temps are the same if not 1-2º better. I wonder if the pump cant get full power from any of my mobo fan headers, despite their being no control on them at the moment

Got it in push pull today too with 2 akasa apaches, havent noticed any diff in temps though, so i'm a little dissapointed and 25 quid lighter. I've got them blowing from inside to outside. Is this the correct way for push pull or should it be blowing inward?

corsair say you should use the rad as an intake but to be honest reading test again only couple degrees in it. So if it suits you better to have them as an exhaust then shouldnt a problem. What were you running when you didnt notice a difference in temperature? would expect a a degree or two difference.

The single Corsair fan as intake, might swap them round and have a play, see if I can squeeze anything more out of them

Not impressed how much RPM i'm having to run the Apache's at to keep the temps below 40, they're quite audible now :(
 
I meant as in programs or stress tests as I only see a difference in temperature when using push pull when my temps start getting higher (i am using mine as in intake) How are you running your fans? I am suprised you have to run them as fast as you make it, what rpm are they running at? For me as I am typing this my cpu fan is showing as 680 rpm and fan controller is set at 690 rpm and noisiest part of my system is the 200mm fan on the front.
 
Hi jim.

Ive had a good read through.

Your h50 is fine mate. Mine buzzed and made weird noises!

The temps are also fine. I had one in my i7 920 running @ 4.2 my temps were not amazing but they were touching sort of 68oc on full load. I think i expected too much from the corsair h50. But by todays standards its still the peoples choice for cooling there cpu.

If you have not already i would invest in some decent fans for push and pull.

Can i ask what case you have and what sort of intakes and outtakes you have? Also is the pump running @ 100%?
 
The pump might be buzzing because it is under PWM control which apparently has the tendency to make things buzz because the power goes up and down by minute amounts (this is drawing from my limited electronics knowledge). When you supplied the pump with 12v power, the buzzing stopped because it is being supplied with constant power that does not fluctuate.
 
That could be the reason but a lot of peope run them off pwr_fan which should be 12v constant. The buzzing seems to just be something that the H50 does. I don't know why the buzzing would stop though once plugged via a molex.
 
Greb, I had it running off of PWR_FAN originally as I was led to believe that it was a full 12v but it still buzzed, read a lot of people on their forums putting it direct on molex > 3pin and it stopped, so i tried it and result!

Also managed to drop idle temps from 41 to 36 by changing the apache push pull to intake rather than exhaust

It's all good now!
 
Hmmmm interesting, I have enough molex to fan plugs so might try it next time I open my case see if it reduces/removes the buzz.

5C is a nice drop in temp, hopefully your apache fans are running quieter now too.

ideally you want it blowing from outside through the radiator to inside but it depends on how the rest of your case fans are set up......you dont want to cause the fans to be redundent because there blowing against each other. does your case have a fan at the top?
glad to hear you have stopped your buzzing noise
 
Im glad someone else thought the mounting plate looked wrong when installing. I have the H70 and a 775 board and I thought i'd screwed up at first. I also have the Corsair 600T. As you mentioned there is not much thread on the screws to mount the fans/radiators but they all seem to be holding fine on mine. I have installed as per Cosair instructions and got the air blowing in. My pump seems whisper quiet though. I was dissapointed that I could not here the trickle of water afer all my efforts and only ever using HSF setups before.
