Cooling Fan For Hartke Amp

[Thunderbird]

Hi all I need to replace the cooling fan on my Hartke HA2500 head I have googled and seen lots of fans but dont really know what I need I dont want to get a replacement from Hartke as I would like something that is a lot quieter than the stock fan I am OK with soldering connectors onto a new unit so any idea what fan would be suitable thanks

Can you remove the current fan and check its spec ? A bit of sleuthing suggests that Hartke use 24v 0.15A  brushless DC fans in a few of their amps, so the HA2500 should be the same.

Then it's a matter of buying a noiseless one of similar spec - it might be worth talking to Hartke to see if you can get the flow rate of the current fan as it would be best to match it with the replacement.

Hope that's of help

If it helps, air flow is usually measured in cfm - or cubic feet per minute

I've got a 24v brushless motor fan somewhere at work, think it's 100mm square. They are fairly quiet, can't say if it would be any better than what you currently have, but you're welcome to it if it suits.

Thanks that's a really kind offer 😀 but I am afraid that is too big but I think hartke are sorting me out they are trying to source the part as there is a couple of different options but thank you anyway

I know this is a 3 year old thread, but I thought I'd post this for people who had the same issue in the future.

I purchased a Hartke Model 2000 Transient Attack head and it was kind of beat up and dirty, but everything worked.  The only problem was the fan.  The noise was unbearable and I couldn't take the racket or my bands ridicule.  I called Hartke and they said they don't carry parts for amps from the previous millennium so I was on my own.

I opened the case and found that the fan was the exact same size as many PC Case Fans (80mm).  The only info on the fan itself was that it was brushless and 24v.   I found an old PC Case fan that was 80mm, brushless, low noise, long life, but it was 12v not 24v.  Also the connector to the amp motherboard was different than the PC fan power connector. 

I did a search about voltage differences and on one forum a member said that the fan would would only use the voltage it needed, so in this case the voltage shouldn't be a problem.  It was worth a try.

I snipped the connector off the old fan leaving 3-4 inches of wire to work with, then did the same with the PC fan connector and wire.   I then attached the connector from the old amp fan to PC fan, mounted it and plugged it in.  I crossed my fingers and hit the power switch and to my delight there were no flames or massive electrical arcs coming from the amp.  Just a very light whirring noise.  Success!

I used the amp for several hours of practice at home and a three hour rehearsal with the band the next day, noise and ridicule free.  Some times you just have to make do and this did just fine.
