Sailing_Nut Posted January 24, 2022 Share Posted January 24, 2022 I have an Alphacool ES flow and temperature sensor in a custom cooling loop. I want to know how/if I can enter values that convert the RPM signal to L/H values as specified by Alphacool. Thanks in advance! Quote Link to comment Share on other sites More sharing options...

Sailing_Nut Posted January 25, 2022 Author Share Posted January 25, 2022 Thanks for the info, but I was more asking where in Adia64 I can enter the information. All I see is the ability to create a "correction" in the settings with a ratio and or offset. To even begin to see if I can calculate a proper offset I would need to know the current curve that Adia64 is using. Also, if the flow sensor isn't linear or a different linearity than what is used in Adia64 it won't work with one simple offset. Quote Link to comment Share on other sites More sharing options...

Also, if the flow sensor isn't linear or a different linearity than what is used in Adia64 it won't work with one simple offset. AIDA64 doesn't use any curve. When it shows a RPM reading, the direct (raw) RPM value comes from the sensor that provides the reading for it. You can use the AIDA64 Correction facility to apply a ratio and/or an offset to any given reading, but you cannot convert a reading to go from one measurement unit to the other.

Arctucas Posted January 25, 2022 Share Posted January 25, 2022 Say you have 1100 rpm when you connect the flow sensor to a fan header. That would be ~255 L/H. In AIDA64 you would determine which fan header was reading the flow sensor, Preferences>Correction>New Fan (X), To convert RPM to L/H, (255÷1100 = 0.231....) Enter .231 in the ratio field, and you should see 255 value reported by that sensor in Sensor Panel. Then rename the Fan to Flow or whatever.

Sailing_Nut Posted January 27, 2022 Author Share Posted January 27, 2022 @Arctucas Thanks for the information! I'm a bit confused because I already see the RPM and Flow in Aida64 without me doing anything. In thinking about it, my mobo must be reporting these somehow that Aida64 is picking it up. So, I really need to get the values reported from my mobo correct. The odd thing is that the value I see in Aida64 is 51 L/H but the Asus tool is reporting 8 L/M (480 L/H) Quote Link to comment Share on other sites More sharing options...

I have no clue as to the Flow Sensor reading, perhaps Asus could answer what is happening there? Frankly, I never had faith in any Asus software, but that is just me.

Rash Posted March 14, 2022 Share Posted March 14, 2022 hi, I did the math, ratio 0.17 offset 66 seems to fit best Quote Link to comment Share on other sites More sharing options...
ldwilliams.uk Posted March 12 Share Posted March 12 (edited) A friend says that ratio 0.18, offset 10 fits well Correction to this - Alphacool look to have changed this, these are the corrected figures - Ratio = 0.1709018653 Offset = 63.94619272 Which produces the following results - not perfect, but usable I feel 'rounded' is the result that would be shown. RPM L PER HR rounded 35 75 70 80 80 78 100 85 81 127 90 86 156 95 91 188 100 96 215 105 101 255 110 108 290 115 114 320 120 119 350 125 124 380 130 129 420 135 136 485 140 147 515 145 152 560 150 160 580 155 163 605 160 167 630 165 172 660 170 177 675 175 179 695 180 183 720 185 187 745 190 191 775 195 196 810 200 202 840 205 208 860 210 211 885 215 215 915 220 220 940 225 225 955 230 227 975 235 231 1005 240 236 1035 245 241 1075 250 248 1100 255 252 1130 260 257 1160 265 262 1190 270 267 1220 275 272 1260 280 279 1290 285 284 1320 290 290 1350 295 295 1380 300 300 1410 305 305 1440 310 310 Edited March 25 by ldwilliams.uk Alphacool have revised the product, resulting in new formula Quote Link to comment Share on other sites More sharing options...
