Iteken Posted February 4, 2013 Share Posted February 4, 2013 Hi. i've recently fitted a H60 into my Fortress FT-03 mini case and am having a bit of an issue with the level of noise being created. It's plugged into the Motherboard's CPU fan, and with the default settings / cables the Pump is running at a little over 4600 RPM, generating a high-pitched whining sound (though the CPU is definitely cool!). I fitted a fan controller in line to test the noise output and discovered that when dialled down to ~3000 RPM the pump is "quiet" and still just about provides adequate cooling. As this is my first foray into water, I am a little disappointed at the noise levels so want advice as to weather it's supposed to be that loud, or if my unit is somehow faulty ? Thanks in advance.

peanutz94 Posted February 4, 2013 Share Posted February 4, 2013 Just hang on for a little while...there is a FW update coming out soon that will adress that issue. Just do not run it much lower than 2000RPM or you risk not having enough flow to keep the CPU cool. It's plugged into the Motherboard's CPU fan, and with the default settings / cables the Pump is running at a little over 4600 RPM, generating a high-pitched whining sound (though the CPU is definitely cool!). You have one of the MB's that doubles the actual RPM range. It should be between 2000-22300RPM. So just make sure you set your no lower than 4000RPM in your BIOS . At 3000 RPM's that would mean the pump is only running at 1500RPM actual and is WAY too low to cool correctly. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 4, 2013 Corsair Employee Share Posted February 4, 2013 This is an H60, I don't think it requires FW update. Where the noise coming from? The pump or the fan? H60 comes with the PWM fans that needs to be connected to the CPU_fan header. Make sure that you enable Smart fan/Q-fan in the BIOS to change the fan's rpm based on the CPU temp. The pump needs to be connected to a PWR_fan or SYS_fan headers and needs to run at 4200-4600 at all times. Link to comment Share on other sites More sharing options...
Iteken Posted February 5, 2013 Author Share Posted February 5, 2013 Hi Ram-Guy - thanks for the reply: To answer your questions in reverse order: 1. When connected to the CPU fan socket it runs at 4600 RPM according to my system monitor. 2. Smart fan/Q-fan is enabled but doesn't lower the speed much below 4500 RPM with extreme adjustment to the profiling. 3. The noise is coming from the pump (i guess) on top of my CPU. The actual Fan is not fitted as i'm using my case's 14" fan to cool the Rad as per this pic (Though the fan / rad is eventually at the bottom - that case is sideways): http://onebit.us/x/u/itiken/B3digDXM7P.jpg The noise generated from the pump jumps from "inaudiable" to "annoying" at 3000rpm Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 6, 2013 Corsair Employee Share Posted February 6, 2013 Correct me if I'm wrong but it sounds like you have the pump connected to the CPU fan header. If so, then it will surely drop your pump speed when Smart Fan/Q-fan enable causing the pump to run at a lower rpm. 4600rpm is the pump speed and not fan speed. If it drops to 3000rpm, that will surely cause some noise coming from the pump's impeller. Link to comment Share on other sites More sharing options...
Iteken Posted February 8, 2013 Author Share Posted February 8, 2013 Not quite. Let me try to explain more clearly: The H60 3pin is connected to the CPU fan header socket. The Stock Corsair Fan, attached by default to your H60 is not attached to anything, it's on a shelf. The radiator backs onto the case's 140mm fan - which is in turn connected to the Secondary Fan out on my Motherboard. Without anything else enabled, the Pump runs at ~4600rpm. With FanQ enabled this drops down at rest to around 4400RPM. At both speeds above, the Pump on the CPU Block (or whatever it may be) makes an extremely loud and irritating buzzing/whining noise. For instance it is clearly audiable across the room, over the noise of a 6600GTX running at full blast. The only way to stop this is to add a manual fan controller and crank the voltage/pump down to below 3000 RPM. Reading all your documentation, it seems 4000+ RPM is the recommended speed, yet I cannot believe that the piercing bussing noise (around 3500 Hz) is intended.

Corsair Employee RAM GUY Posted February 8, 2013 Corsair Employee Share Posted February 8, 2013 I would suggest that you get that unit replaced. Use the link on the left to start an RMA process. Link to comment Share on other sites More sharing options...
