500-2K RPMs seem to be the normal range for all Pumps and should be relatively quiet at those speeds. Pumps should run at full tilt, for maximum liquid flow. So the case fans need to run higher, wheras the AIO fan needs to run slower, and so too for the AIO pump speed because I can hear it too at max speed. But a pump on an AIO should run at 100%, 12V, full speed anyways. I noticed that 1 of my exhaist fans that I've plugged into on the AIO pump fan header on my ASUS Z270H motherboard is spinning at full speed and I am not able to configure it in the BIOS. Connection: - 3PIN connector of the CPU block to CPU/CPU1 header on MB I have the recent ocuk 6700k bundle with 120mm cpu aio cooler, I was wondering if is ok to vary the pump speed or should it be at 100% constantly (mainly a question about not damaging the pump). You HAVE to tweak those things in the BIOS. BOT:Leave it at PWM, thats what most recommend, if the pump itself is making clicking or tapping noise then you have a concern as that is signs of pump failure. This is because it is (or should be) so quiet it doesn't matter and it assures instant cooling when the processor starts working hard. HAve just upgraded my motherboard but can't get the AIO pump to run at full speed. Otherwise, the pump won't get the full 12V that it needs. However, until it's getting the full 12V, it won't operate properly. Are you seeing higher than normal temps? That's required for it to read the fan speed and control the fans. The AIO has its own control and will increase as needed based on the CPU temperature. HAve tried connecting the pump to the pump header, CPU & CPU OPT header. That would feed cool air into the case and keep the AIO happier at a lower speed. Hi, so I recently finished my build and turned the system on for the first time. This is very similar to most all AIO coolers out there as we work with Astek on this product. Abrasive wear is proportional to the fifth power of the velocity / speed. Please check the setting in Your bios for the CPU fan header, Q-FAN or any fan control option should be "off", manual (100%) or full speed (max) - I don´t know how Asus calls these exactly. 5. Is there any way I could solve this or should I just leave it running on full speed? Tested a fan on all headers and the speed is adjustable so the headers are not faulty. So whatever options you have in the Flow Control software, try to set a 90% pump speed for a 60c CPU die/package temperature. Performance mode RPM should be around 2760 (+/-30) RPM in Corsair Link. This generally means the pump rpm will be anywhere from @1200rpm to almost 4000rpm depending on the pump, so 1600rpm sounds about right. You cannot push the pump speed to 100% if … So this fact gives you many choices. Todays chips and motherboards will shut down before damage is caused. Not the AiO liquid temperature, but use the temperature sensor for the CPU itself. Unless specified as a variable speed pump (common on fractal design and nzxt Kraken), you should run aio pumps at full 12v. That is why most AIO coolers (minus digitally controlled models such as corsairs I series) have their pumps attach to a 3 pin fan header, to run at 100%. Abrasive Wear: Now for pumps that handle abrasive liquids, speed / velocity is a major factor in determining the wear rate. The pump noise, while not "loud" is annoying in a quite room. Pumps intended to handle abrasives should, therefore, operate at the lowest practical speed. I tested temps with the pump running at max speed and with the pump dialed back to position "3". In bios have set the q control to 100% butt still will only run at 1500rpm. CPUs can certainly run hotter and be safe, but 60c is typically the target you want to shoot for under a gaming load. Second, make sure that the fans are connected to the fan headers coming off of the pump.
