HR24 Fan Repair?

They wouldn't guarantee the replacement would be the same model and they wouldn't waive the shipping fee. They also wanted to extend my contract so I declined the replacement. I tore a case fan out of an old Macintosh G3 and have it running on the left side pulling air through the DVR. Temps are holding at 104F. Solved.
While not being able to guarantee the same model, and charging for shipping isn't a big suprise, the extended contract is 100% wrong. If you are replacing a defective receiver your contract is not extended.
While they can't guarantee the same model we have been told that they actually do make an effort to replace HR24s with HR24s (you might get a -200, or 500 instead of a -100). However, I believe if the warehouse they are shipping from is completely out of HR24s, then you will get whatever they have in stock (HR21, HR22, HR23) they won't wait until they get more HR24s in to ship you a replacement.

Sorry to revive an old thread, but it is exactly on topic.
The fan in my HR24 died (it gave some notice).
The machine now likes to give me an overheat notice.
I opened the case without incident.
I ordered some new fans and noticed that the wiring seems to be the opposite colors given the location of the pug (i.e. the white and black wires have their positions reversed).
When the new fan is placed in the system it doesn't spin up on boot and appears to not spin at all.
The original fan in my system was the version with the rounded corners; the new fans were the square cornered versions. I have a few of the rounded corner versions on order, but shipment from China is extremely slow.
So, do I have the wrong fan due to the wiring or is there potentially something wrong with the plug/board. I could get a Genie, but I'd rather not retrain the family <g>.
The temp was 115 degrees before I rebooted a moment ago.

swap the wires; if you'll look close , there are small metal flaps holding pins, gently push down, extract the pin with a wire, swap them

12V DC, .08A. 3 wire.
If you don't have the exact replacement it still may work. It is good to know that the 3rd wire (usually white) is probably a sensor wire. Pro servers use this to monitor fan speed. It may not really connect to anything in a consumer DVR. If it does, it may throw a lot of errors, but probably behind the scenes if it does, meaning you probably do not need that third wire. A conventional 2-wire will probably work OK.
In a HP Proliant server the thing will beep at you continuously if the 3rd wire is not connected (if you try to use the 2-wire fan). It thinks the fan is dead if it does not see anything on the third wire. We had one beeping for months before we finally got the right replacement fan installed.
One more thing, if your fan is dead but still spins freely, you can hot-glue a replacement on the outside as long as you have a 12v source to run it. If the old fan does not spin freely, you can still do this, but the old fan somewhat blocks the airflow from the new one. Good for those too nervous to open the lid.

OK, I ordered two different sets of replacement fans. The first ones were square and I needed to round off two corners - these had the wires reversed. I haven't tried to swap the wires.
The second set, with the rounded corners arrived today. These have the wires in the same place as the dead fan. Upon putting the fan in the HR24 and re-powering up, the fan doesn't spin upon boot.
Is there something further I should look at? I was under the impression that these fans were spinning ALL the time - perhaps with the third wire it is a heat issue and will spin/change speed as needed (I hope)?
Suggestions welcome - I really don't want to upgrade to a Genie at the moment. I can't put the cover on the HR without the fan because it will certainly overheat.

OK, nevermind. After some fiddling, I see that the fan IS now spinning (on the rounded corner replacement fan). It is really silent.
Can someone tell me what a 'normal' range of operating temperature is so that, now that the lid is on, I can check to make sure the airflow/temp is sufficient?
Anyone want some HR24 fans that need the pins swapped?
