![]() ![]() #2 I haven't used it before so I don't know how effective it is but having dynamic RPM case fans doesn't seem ideal. If I jump into Smart Fan 5 and turn this up to 100% I can hear the pump ticking over and the CPU fans running full speed. Do you have a separate readout of the pump speed and/or voltage? I would try plugging it into a different header, maybe just a regular one on the mobo? #1 If your AIO cooler is installed correctly, I'm guessing the CPU_OPT is adjusting pump speed. I can get a reading for this which shows flow rate of 22 L/min and RPM of 1900 in BIOS. Thus the only cable from the CPU cooler is to the CPU_OPT header on the motherboard. So I figure this means the case fans being 3 pin will all just run at full speed? There are no fan readings showing up for CPU_FAN but they are definitely running. I don’t think this will receive a signal unless I also plug a PWM fan into the case fan header. There is also a PWM cable which is in the CPU_FAN header. The case fan header gets it’s power direct from a SATA power cable. So I’ve got the all the case fans plugged into the case fan header. Originalmente postado por h_LordEC:Wait, you have all the fans controlled by the CPU temp which is based on the CPU_Fan speed but have only a pump plugged into the CPU fan headers? Happy to troubleshoot anything or provide more information to try and resolve this! Greatly appreciate any suggestions and help. I've noticed that BIOS and Gigabyte's Smart Fan 5 seem to indicate the processor is at least 10 C coolwer than what MSI, and RealTemp report. Sometimes opening a simple Windows app can spike it for a few seconds or keep the fans running high. Total War: Warhammer 2 - CPU 65 C (75 loading maps) GPU: 80 C (in campaign map)Īs for the CPU spikes, I can't explain it. Warhammer Vermintide 2 - CPU: 55-68 (changes instantly) GPU: 74ĪRMA 3 - CPU: 55-65 (instant shifts), GPU: 70 Total War: Thrones of Britannia Benchmark - CPU: 55 GPU: 72 Mass Effect Andromeda - CPU: 65 GPU: 80 (within 10 minutes: ) Idle - CPU: 40 C GPU: 55 C (GPU cools down quickly, CPU takes some time) Some rough temperature measurements using MSI Afterburner on screen display: My understanding is that the GPU will warn me at 85 C? Even a quick in-game benchmark is enough to get the case fans roaring with temperatures hitting 80 C forcing me to quit my game before it gets higher. I've noticed that some games are getting the GPU to temperatures of 70-80 in less than 5-10 minutes of gaming. Problems I'm having: Odd CPU temperature spikes, causing fans to rev quite high momentarily and overall poor cooling performance. The pump is connected to CPU_OPT (immediately below CPU_FAN) as it doesn't reach the spare 4-pin header on the fan hub (indicated for pumps in manual). The case fans are all 3-pin so they should increase RPM when the CPU fans do. The soundcard is mounted on the lowest available motherboard PCI-E slot leaving a decent gap (a few inches) between it and the video card mounted in PCI-16x.Īs far as I understand the fan hub, it takes its information from the CPU_FAN header and uses that to determine fan speeds. The system has an optical drive but only 2 SSDs in their own trays just below, with a lot of distance between each other. In terms of case airflow, I thought I did a good job keeping things clear. I'm a bit worried with 2 140mm intake + 1 240mm radiator intaking vs 3 140mm exhaust fans I might see negative pressure? I'm about to test mounting the radiator at the front for intake, and putting the current 2 140mm intake fans on the top for exhaust. Changing CPU cooling to exhaust instead of intake has seen CPU temperatures rise about 5-10 C which is a little higher than I expected, and GPU temperatures remain unchanged. Initially I thought this might have been the cause of the high temperatures but it doesn't seem so. The radiator for the CPU is mounted at the top with 2 Dynamic X2 GP-12 PWM 120mm Fans exhausting air, originally I had this configured to intake air as the manual suggested, however that would leave only 1 fan exhausting air out of the system. The exhaust fan is also an X2 GP-14 140mm fan mounted at the rear. The intake fans are Fractal Design X2 GP-14 140mm fans, 2 mounted at the front and 2 at the bottom. I've got the case configured with 4 intake fans and 1 exhaust fan + 2 exhaust on the CPU radiator.

First time building a new PC in many many years and I'm struggling to achieve sufficient cooling for this system. ![]()
