Hello, I'm having trouble finding a suitable replacement cooling fan for my Dell 2400MP DLP Projector. A few months ago I began experiencing problems with the lamp overheating and determined that the cause was a malfunctioning cooling fan, which I was able to determine was manufactured by Sunon. The part number I believe is PSD1208PTB1-A, but I have been unable to find this part anywhere, including Discount-Merchant.com and PartStore.com

I attempted replacing the fan with another fan of the same dimensions, which are 80mm X 80mm X 25mm, but found out that it did not have a high enough airflow and once installed in my projector the lamp continued to overheat. At this point all I know is that I need a fan with those dimensions that is powerful enough to cool the projector's bulb but I'm not sure where to find one, and exactly how "powerful" is powerful enough. Would I be wrong to assume that any fan with the same dimensions and a high enough airflow will be a suitable replacement?

Any help is appreciated. Thank you!

Here are photos of the old, busted fan:

It isn't just the correct size and airflow, you have to have a fan that has THREE wires, projectors use fans that have a feedback loop so the projector knows they're on. Without that, it assumes a failure and shuts down.

However, you may be in luck. A couple of 2400 units were retired out a sports bar because of shattered color wheels. I may still have them in my back room. I'll have to check to be sure they haven't walked away.

Of course, having said all this, there is no guarantee that it IS the fan that failed. What IS common is the fan controller fails and those are not serviceable, the entire main board would be replaced.

Those fans generally run on 10 - 15 volts dc, depending on the projector. If you haven't done so already, I would first test the fan to see if it runs when power is applied and go from there.

Sheridan - I just checked this thread and saw your response for the first time. It's been a while, but if it's still an option I'd be very interested in buying one of the fans out of the busted projectors you have kicking around. Let me know if you were able to locate them!

Thanks,
Ben

Hello, I found the replacement at SUNON for the PSD1208.
http://www.aliexpress.com/fm-store/505260/210131733-504569235/Original-SUNON-8CM-cooling-Fan-12V-PSD1208PMB1-A-Air-flow-Fan-cpu-cooler-heatsink-axial-Cooling.html
But the question is how to check the total chain. This Fan is part of an electronic control sequence and I wonder if the fan is the malefactor. Is the service manual available?
