EK Vardar 120ER EVO start up behavior

Hey guys,

I am curious on how the EK Vardar 120ER EVO operate. Especially how they ramp up in speed once powered up.
I have 12 EK Vardar ER (non EVO from 2017) that start at full speed even if the PWM cycle is at 50% and then slow down to the PWM setting. It is pretty annoying and usually trip the overcurrent protection on the fan controller (when tying up 6 on an AQ6 channel).

Do the EVOs do the same?

Thanks

Yep mine do. Only goes for a few seconds before the AQ kicks in

Never had them trip the over voltage and I have 6 per channel as well.
Even have a pair of 6 on a Quadro
Using splitty9’s?

Yep Splitty's. Support told me that the controlling chip may be damaged in the AQ and this is usually not covered by warranty (because of bad behaving fans - go figure). So I haven't RMAd it.

So, you say that your EVOs ramp up at full speed when powering on even though the PWM duty cycle is not at 100%?

Another thing: AQ kicks in well before sending voltage to the fans. You can confirm the behavior by unplugging and replugging the fan while it's running (it will start at 100% and drop down to the PWM setting).

(note: it's overcurrent not overvoltage)

Yep all of mine do that. Least I think they do. Don’t have my rig up and running atm so sorry for the late reply.
I’ll test it out next week when I get it running again but as far as I can remember they start up at 100% then drop down to the AQ settings after a few seconds.

Thanks for the info. Appreciate it.

If that's the case, they're not for me as the ones I already have do the same. I measured over 3 Amps for 6 fans connected so that is bound to create issues sooner or later (as it did with my AQ6). I moved them on the Quadro, but I expect it to fail the same way down the lane (AQ6 failed 2 days after 2 years).

Just wanted to say using an aquaero 6 my evo fans do not ramp up when they start spinning which they shouldn’t at least. Now my ER fans I have 3 on one radiator that don’t ramp up. They can stop spinning and then start back up spinning very slowly. Another 2 ER fans ramp up and the only way around it that I found was to set a low minimum pwm % like 10 percent for those fans, or set them as speed or power (voltage control) and they didn’t ramp up. Personally I stuck with the minimum pwm % since they spin at about 300rpm.

That's exactly how my fans operate and how I managed to work around this issue. But, the problems I am experiencing with AQ6 are at cold boot unfortunately.

It seems that they have multiple iterations for these fans and this behavior is not mentioned anywhere. Not even the EK support people know about this. Just wish I had properly tested the fans before mounting them...

Thanks for the info guys.

Hi there

I have only tried or run 6*EK Vardar F3 1850RPM on my loop and X99 ASRock X99 Extreme6 and Aquaero 6 XT and must say on this build no issues with fans ramping up during the boot up or during the cold boot, never run to issues with them, only one thing I hated on these fans which have been whining noise in some specific RPM and overall loudness of fans

On other build where friend has run Asus Rampage V Extreme and there we are run Aquaero 6 Pro with similar fan setup and radiator setup(360mm on top and on bottom 240mm 60mm thick radiator), on top we are run Phanteks PH-F120MP and on bottom 240mm 60mm thick radiator we are run EK Vardar F3 1850RPM which would ramp up during boot up to max RPM and then during Windows logo fans would return to normal PWM settings, sometimes fans wouldn't slow down to normal PWM settings unless you are try again set them in Aquasuite to PWM

Hard to say why these fans responded so differently on Asus Rampage V Extreme and ASRock X99 Extreme6

Hope this helps

Thanks, Jura

isn't the ramping on boot an inherent system thing, due to getting power before settings click on?

also - doesn't aquaero include a delay start option?

I feel like my fans have always span at max speed briefly on boot and always thought it was related to the motherboard or inherent system designs. It's not something I'm very knowledgeable about, but I'll do my best to help find a solution if you haven't found one yet.
