Ensoniq ASR-10 rackmount is very hot

Post by thunderheart530 » Mon May 18, 2020 2:27 am

Does anyone who own's an Ensoniq ASR-10 have a solution for the amount of heat this unit produces? the front panel around the transformer gets very hot after a few hours and they decided not to put any vents on the top. I talked to a tech and he said if I tried to add a fan it would most likely add noise to the signal. Has anyone bothered to do this?

Following. The keyboard version was my largest hammer in the mid to late 90s. Got a great deal on a rack a couple years ago, but it has button issues. I’ll be looking at possibilities when I have it open again.

The obvious solution would be to drill some strategically placed holes to aid convection. Probably lots of tiny holes- to deter spiders and dust from invading the chassis. I hate adding acoustically noisy fans to things, so I don’t care whether a fan would be electrically noisy or not.

The bad news is that ASR-10 racks that run to hot are prone to crash, and there is not a lot you can do too cool it beside drill holes and install a fan. I had enough trouble with it that I downgraded to an EPS16+. It will be somewhat better if you do not install it in a rack with other units adjacent to it.

Pulling it out of the rack has definitely helped. I also put it in a spot where I can access it with ease as I have been using it so much lately.

About drilling holes, Maybe taking the top to a shop and having it professionally cut might be the best option? Also putting some sort of foam inside to keep dust from getting it.

I think foam would block convection and act as an insulator. If I do decide to drill holes, I have adequate tools to do a good job.

I’m planning to continue using the open-frame rack it’s in now- I haven’t noticed excessive heat, but will be keeping a closer eye on things..

My rack is similar to this, but I think it cost less:

How much free rack space do you leave above and below your ASR10?

Could you leave 1 U above and below it, and buy some vented 1U panels to cover the gaps?

I actually decided to separate the unit from the rack for now. I'm going to look for someone who can modify the top around town.
