HR24 eBay Fan
Wrong fan - EBay

Right fan
JMC Part No: 05001A0038
I ordered the HR24 fan from eBay seller "justpal." It arrived yesterday.
It is smaller and doesn't have the beveled corners. It's too small to firmly fit into the fan cradle and basically sits there loosely. If the HR24 were moved, then it would fall over, unless it was glued or double sided taped down.
If you could get it glued or taped down, it's size causes me to wonder about its CFM ability.
The three conductor plug on the wire does snap into the receptacle.
Wrong fan - EBay seller "justpal". JMC Part No: 04000A0034, Model No: 4010-12.
Correct fan - JMC Part No: 05001A0038, Model # 5015-12.
Breakdown of model numbers
Correct fan
5015-12
50 (50mm H x 50mm W), 15 (15mm D), -12 (12 volt DC Voltage).
eBay Fan
4010-12
40 (40mm H x 40mm W), 10 (10mm D), -12 (12 volt DC Voltage).
Both fans draw 0.08 amps.
I have uploaded a picture of the two fans, side by side.
The eBay fan, JMC Part No: 04000A0034, Model No: 4010-12, is on the left side of the picture.
The fan that I actually need, JMC Part No: 05001A0038, Model # 5015-12, is on the right side.
I also uploaded a straight on picture of the connector.
I suspect that JMC # 05001A0038 is a discontinued item and DirecTV probably changed out the fan to a newer fan that was readily available in the Supply Chain.
I am also exploring getting a 50mm x 50mm x 15 fan from an alternate source.
I noticed on Partstat.com, an Electronic Components Search Engine that a Global Supply Chain Company, Celestica Inc, is sitting on a Qty of 5007 of these fans. I suspect that they will sell these in volume only.
I took the chance and called their Austin Sales Office and left a message with a callback number. Maybe I will ask for a sample if I can get through to the salesperson.
The seller did caution in his auction that there were two different fans for HR24. I thought that the differences were the beveled corners. The correct fan is larger.
It appears that most of the heat in the HR24 is generated by a CPU with a heatsink that touches the 500GB Hard drive and transfers heat to the 500GB hard drive causing the hard drive to get hot. The fan is located close to the hard drive. Unsure if the fan blows air towards or away from the 3.5" hard drive.
I am also surprised that the cooling system of the HR24 wasn't given more thought.
Below are my observations of design flaws of the HR24 DVR.
1. There is too much reliance on the only fan in the box, which is cheap. I got this DVR less than two years ago, and the fan has already failed.
2. The CPU has a heatsink only. There is no CPU fan on top of the heatsink.
3. The heatsink on the CPU sits right next to the 3.5" hard drive and touches it, causing the hard drive to become a surrogate heatsink. I supposed if DirecTV switched to a 2.5" laptop hard drive, then this would eliminate this problem.
4. There is no exit and entry fans to suck in cool air and blow out hot air.
Overheating is probably the biggest reason for hardware failure. A good cooling system is sometimes an after thought in hardware design.
I work for a Telecom Equipment manufacturer and have seen poor cooling system design in some of our products.
I will contact eBay seller 'justpals' about getting an RMA number. I had bought two fans thinking that it was a sure thing.
I am ready to get the HR24 replaced under warranty. Wife is giving me a hard time. I just don't want to lose the recordings and the playlists. This is the main reason why I am seeking a replacement fan.
I use this DVR for my shows and movies. The 2nd DVR, which is upstairs has my wife's shows, and the third DVR in the front room has the kids shows and playlists. My wife has hinted that the kids DVR is also showing temperature messages too.
Since we have Whole Home DVRs with three HR24 DVRs, it would be nice if DirecTV had added a "Migration Feature" that allowed the ability to move the stored content and configured playlists from a DVR that will be decommissioned and placed onto another DVR on the Network or placed onto a DirecTV App running on a PC or MAC.
When the replacement DVR shows up, connected, and provisioned on the account, then the stored Content and Playlist could be restored onto the new DVR.
I hope that DirecTV reads the postings in these forums.
