I just wanted to make sure nobody thought Richard was putting out junk. :+1:
IF they are installed properly, the height of the button makes no difference…… as long as there is room for good contact.
IF NOT installed properly, it could & would most likely make a world of difference…. on either one.
I was not disagreeing with you, my preference is like the ones on the right too. BUT the ones on the left are just fine if installed properly.
Yeah blinker, as has ready been said; two seperate issues. If yours ain’t broke, don’t worry about it. BUT, IF you determine yours has one or both of the issues, these two threads have the answers.
For instance, my 3100 v2.2 had the crappy powersupply issue; which was remedied by thr LiteOn power supply. But I had no issue with cooling.
IIRC chops chargers had no issue with either, while wolfdogs had issue with power supply & cooling.
Just figure out where yours stands and if you need to fix eithet of these two issues you have all the info you need to do so right here in these threads.
Did you look into other fans before deciding to purchase the Delta? I know Delta is a trusted name but their fans are really loud. A quick search turned up a few fans that have higher rated CFM although I’m not sure if we can trust their specs.
I have contacted Henry 3 times since August 25,2017…about every 10 days after the initial email… NO REPLY
I am baffled why all of the sudden he does not respond. We exchanged dozens of emails in April and May of 2017. He was very efficient and prompt,no more!
Did something happen to him? Did he get another job?,If so,someone in the company probably would have responded.
The fans I am looking at take about 0.45 W at 12 VDC. It is one of the Sunons in a link above. It is much quieter that many others. 16 dbm, 3 CFM.
How much power is available from the 12VDC feed going to the OEM fan?
Second is kind of an idea around the same fan. There is a version of it that uses a third wire for speed control. Using that version I could just tie the fan to raw DC, and use the controller. The question in that scenario is what does the output of the fan driver in the charger look like. Is it PWM, or just a variable DC output being dropped by the resistor that is in series. If I can use a third wire for a low power control signal, it eliminates worrying about the power available from the original driver.
… I’m good.
