blachbamse Posted October 25, 2018 Share Posted October 25, 2018 https://imgur.com/a/qwaA001 Is it installed correkt? Fans are not same speed.. I can only control one.. Link to comment Share on other sites More sharing options...
DevBiker Posted October 25, 2018 Share Posted October 25, 2018 The CPU Fan is giving you a readout of the pump speed / 2. That's not the speed of the radiator fans. And both fans will be the same speed. You only have one control for the fans. The only thing that I would mention is to make sure that the fan that the pump is plugged in to (the CPU_FAN, by default) is set to 100%/Full Speed. See the Liquid Cooler FAQ, Section B for more details. Link to comment Share on other sites More sharing options...
blachbamse Posted October 25, 2018 Author Share Posted October 25, 2018 hmm.. In bios - its PWM OR DC ? Link to comment Share on other sites More sharing options...
DevBiker Posted October 25, 2018 Share Posted October 25, 2018 The CPU_FAN header provides power. PWM or DC is irrelevant in this context as the CPU_FAN header doesn't control the pump speed. That said, setting it to PWM will set it to 12V. However, I would not recommend doing that as some BIOS will automatically flip it to DC mode as it only has 3 pins and doesn't change based on the PWM signal. So the safest thing is to set it to 100%/Full Power, across the board. Link to comment Share on other sites More sharing options...
blachbamse Posted October 25, 2018 Author Share Posted October 25, 2018 But i dont know how... The FAQ doest help that much Link to comment Share on other sites More sharing options...
DevBiker Posted October 25, 2018 Share Posted October 25, 2018 You have to go into your BIOS. And it's different with EVERY BIOS. So the FAQ can only do so much. Check your manual. It'll tell you how to set the fan curves. Just set to the "Full Power" or move the "balls" to 100% power across the board ... or something like that.

DevBiker Posted October 25, 2018 Share Posted October 25, 2018 Two options. Do you see where it says "All Full Speed"? Click that. Other option ... move all of the little "balls" to the top. That's the same as "All Full Speed". Unchecking "Smart Fan Mode" might even work too. It looks similar to Asus' "Disable Q-Fan Control". Link to comment Share on other sites More sharing options...
blachbamse Posted October 25, 2018 Author Share Posted October 25, 2018 Its still the same as before... even after i uncheck smart fan mode in bios Link to comment Share on other sites More sharing options...
blachbamse Posted October 25, 2018 Author Share Posted October 25, 2018 And should there be any difference in noise levels when pump is at performance ? Because there isn't Link to comment Share on other sites More sharing options...
DevBiker Posted October 25, 2018 Share Posted October 25, 2018 A) It's not uncommon for folks to notice "no issues" even when the pump isn't getting enough voltage. What happens is that the pump fails early. Please, leave it set to 100%/Full Power. B) There is a slight noise difference but it's not usually noticeable over case fans and through the case. You'll see higher pump RPMs in Link/iCue. There isn't a measurable performance difference between the two so set it to whatever you like. Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 I'm still not sure, that i've done it correctly... Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 When i try prime95... the fans doesn't follow the mode in LINK. It just stay's at the same RPM alle the time... WTF...! Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 Okay - so it was set to follow the water temp not the CPU temp.. my bad.. But still, and dot know if the pump are working okay Link to comment Share on other sites More sharing options...
c-attack Posted October 26, 2018 Share Posted October 26, 2018 Okay - so it was set to follow the water temp not the CPU temp.. my bad.. But still, and dot know if the pump are working okay No, it is supposed to be set for water temperature. That how’s how it works. The fans do not cool the cpu directly. They remove heat from the coolant. Your increase in coolant temperature is a penalty applied to the cpu. If coolant is +10C, then all cpu temps regardless of load will be +10C higher than they would have been at the start. That does not change on whether the cpu is loaded or not and cpu load is a condition that changes in an instant. Since room/case temperature and your specific case layout play a large role in your actual coolant temperature, you most likely want to make a custom curve that is appropriate for your uses and noise tolerances. The presets are likely too loud for mixed uses like gaming where GPU heat boosts the case and coolant temps as well. Take some time to figure out your normal idle/cool water temp and the peak value you see during real use. Don’t use Prime95 as measuring stick for this, unless your pc has a habit of unexpectedly searching for Mersenne Primes on its own. If you are running cpu stress tests as benchmarks, you should use a fixed fan speed of whatever you choose for consistency and comparability. You don’t need maximal fan speeds for normal or heavy use in most circumstances. A moderate, steady speed should do. Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 Yeah okay... But why are the fan curves set in "performance" to 75 % at water temp above 50 deg. It never comes that high... Maybe my pump not working correctly... Link to comment Share on other sites More sharing options...
DevBiker Posted October 26, 2018 Share Posted October 26, 2018 Yeah okay... But why are the fan curves set in "performance" to 75 % at water temp above 50 deg. It never comes that high... Maybe my pump not working correctly... No, if your coolant temp got to 50C, we'd be worried that either your pump wasn't working correctly or you had airflow issues. The thing is ... after a certain point, more fan speed won't cool things off faster but it will cause a whole lot more noise. Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 Yeah i get that know :) I'll try fixed % any se how that goes :) I guess the pump works fine, when the coolant temp keeps down :) Link to comment Share on other sites More sharing options...
DevBiker Posted October 26, 2018 Share Posted October 26, 2018 Yeah i get that know :) I'll try fixed % any se how that goes :) I guess the pump works fine, when the coolant temp keeps down :) Yup. Just make sure that the fan header that it's connected to is at 100%/Full Speed. It's required ... and not in the manual. Link to comment Share on other sites More sharing options...
blachbamse Posted October 26, 2018 Author Share Posted October 26, 2018 And yet i still not sure that it is... I will try the msi forum... Link to comment Share on other sites More sharing options...
DevBiker Posted October 26, 2018 Share Posted October 26, 2018 Based on the image that you showed earlier, just hit "All Full Speed". Link to comment Share on other sites More sharing options...
blachbamse Posted October 27, 2018 Author Share Posted October 27, 2018 Put then my other fans in front start to speed up as well... and thats to loud! Link to comment Share on other sites More sharing options...
DevBiker Posted October 27, 2018 Share Posted October 27, 2018 Got it. So "All Full Speed" does all of the fans. That's not what I expected. So ... again, back to the image you showed, drag all of the little "balls" on that fan curve all the way to the top. That should do the trick. And, btw, if you update the BIOS, you'll need to check this setting. Link to comment Share on other sites More sharing options...
