I keep forgetting to update my fan swap, as mentioned earlier in the thread here:http://www.avsforum.com/avs-vb/showt...9#post16100289
I didn't have a lot of luck. There are three fans and I swapped in two
replacements. But the projector would shut down after just a few minutes.
So I now have it with just one replacement fan and it's been fine for the
last 1200 hours.
The single replacement fan did lower fan volume an audible level. But the
difference is so slight, that it's not really something I'd recommend unless
you have nothing better to do with your time.
I now have 1800+ hours on this projector and original lamp. I started out
watching everything with the narrow iris setting. But after about 600 hours,
I had to switch to medium iris, where I'm still at today. It still looks great
today, but I'm going to replace the bulb anyways. I'll try the relampit.com
I use a 92" wide DaLite High Power screen and the projector is mounted
about 10" down from an 8' ceiling.
Here are some pics of the teardown, cleaning and fan swap.
VP4001 on left, vs. the Sharp 12k it replaced. The Sharp had a slightly
better overall picture, but was louder and way dimmer.

Internals. You can see the three fans at the bottom:
This is the original fan. Fans just lift right up. No screws.
I like that they are encased in removable rubber grommets:

This is how the fans connect to the circuit board:

The Nexus is the one on the far left.
