Cleaning your W1070 Beamer and Fixing Loud Fan Noise

I’ve got my W1070 about 2 years ago and it has been collecting dust since then as it is being used on a daily basis in a basement. It’s time to clean the inside and finally fix those noisy fans. My beamer is used in a dusty basement and smoking area so I’m expecting to find the worst inside.

Taking apart your W1070

Official Dissemble Manual: Part #1Part #2

First, find the following screw on the left side of the beamer and unscrew it:

Now the lamp cover will come off:

Remove the plastic, unscrew the lamp and remove it from the beamer (Carefully you don’t want to break your lamp):

Then unscrew the top cover screw :

Now turn around you beamer and unscrew these 5 screws:

Gently remove the top and side panels of your beamer, these should come loose with some wiggling, don’t remove the back panel yet (I/O panel)

Remove all side panels except for the connector panel:

Cleaning

First, before touching your beamer you should cover the lens with a piece of tape(make sure the tape does not leave any “glue” when removed) as you absolutely don’t want dust to come on your lens!

After taping this hole, you can use a toothbrush to clean the inside, you can also use a compressor to blow the dust-out but when you do make sure you block all fans from spinning as spinning fans may break your fan or beamer.

Loud Fan Noise

I planned on dissembling and cleaning my fans on the inside to get rid of the rattling sound. However, after cleaning and reassembling the beamer the fans were quite just like new and I didn’t need to disassemble and clean my fans anymore.

– Disassemble/Clean Fans : Guide #1 – Guide #2
– Replace Fans with “Third Party” fans.

Conclusion: I removed a lot of dead flies and dust, making the beamer run silently as it was new and I would recommend everyone to clean your beamer once every year.

HI,
THKS for work.
Only a question, is the fan 80 mm ?
I’m thinking of changing the main fan (lamp one).
Merci 😉

No. It is 70x70x25 mm. I’m thinking of replacing it also, but it’s difficult to find a replacement that is as thick, most 70 mm fans are 10-15 mm. If you find a good fan right dimensions please let us know.

HI,

Did you have any idea about which airflow (CFM) is needed?

I really want to try to change this fan and found a lot of different specification. but I don’t want to create a warm issue if I don’t take the good one

Merci Thanks

It looks like this one from newegg.com will work.

70x70x25mm DC 12v case Fan,EC7025M12CA

It has a lower fan speed, CFM, and db. I’m sure it would produce enough air to keep the lamp cool.

If works i’ll try and update. Thanks for the guide!

Hello Steven,
I’ve seen your video of the benQ W1070 and was thrilled. Where can I get firmware updates for other beamer

I finally changed all the fans, because the projector started to shut down quite often, probably due to overheating. I replaced the speaker on the right side with a fan, plus changed the one fan on the right side for two. So now there are three fans on the right side (right side looking from the front), two blowing air in and one sucking air out. I also added a barrier made of a plastic ice-cream container between these to decrease turbulence. Had to do some minor adjustments to the chassis to fit the new fans. But good news is… Read more »

Thanks for taking the time Steven.. !
my W1070 is a couple of years old and just clocked over 4,000 equivalent lamp hours, and though i have to admit i’m not sure what that means i’m fairly sure it’s overdue for a good cleaning cos it often cops out due to overheating. i hope to find the time soon to do this job and i’ll be back to thank you again after i notice some improvement. all the best, Derek

Good morning! Is the code of this github repo accessible somewhere? Or can you send me the code via email? http://web.archive.org/web/20161221121209/https://stevenbreuls.com:80/2016/12/swift-example-of-libartnet-for-mac-xcode-8-swift-3-0
