That's really cool. Really really cool.
I bought a 1TB new Roamio OTA on BF. Yesterday I unplugged the box and left it unplugged overnight. About 9am I applied power. It was loud. Very loud. I figured that a fan shouldn't fail after 30 days, but I wasn't too surprised either. I left it run for 3 hours. Another 1TB basic Roamio, only two feet away is very quiet. My quiet Roamio has a MBT of 37. My noisy Roamio has a MBT of 33. I think it's loud due to the fan running at full speed. I will have to check the fan, but if the PWM circuit is bad, another fan isn't going to help. This sucks.
I may have to result in external power for the fan. Any experience doing this? I have the needed skills.
My roamio OTA fan had become very noisy after about a year of service. After looking at various YouTube videos, I opened up my unit and found, that with the unit unplugged, the fan was stiff to spin. I pealed off the label on the fan to try to access the bearing, but found there was no access to the bearing, or the cover was not removable. Using a jack knife, I bore a very small hole in the Centre where the bearing should be and could see a cavity. The cover showed no signs of being able to be removed. Other fans I have removed the label and had access to the bearing or a rubber cover that was easy to remove. I placed an extremely small drop of sewing machine oil on this hole and plugged the TiVo back in. It took about 2 minutes of running and fan became quiet again. It has now been about a month and it is still running quiet. I expected this fix to not last very long, but has given me time to find and order a replacement fan. The two factors I must impress on are that the hole I bored into the center of the fan motor to access the bearing is VERY SMALL, and I used only a VERY SMALL drop of sewing machine oil. Other fans I have tried this on did not a long time before becoming noisy again. The main purpose of this was to reduce the noise from the fan and gain time to find and order a replacement fan.
On my Bolt, I have added a 12 volt fan powered by the USB port to blow air over the back of the unit by the coax connector. It only takes a small amount of air movement to keep it cool.
Thanks. I also noticed that the usual warm spot (at the RF connection) is not warm. I have too much air flow.
My first Roamio OTA fan lasted 19 days before it got noisy (bought it from Best Buy during the $300 Black Friday sale). Now the 2nd replacement unit that I got from Best Buy on December 14 is getting noisy after 25 days. It's not as noisy as the first unit when I first noticed it, but it's starting.
Does anyone know if Tivo puts better quality fans in the units that they repair or replace through their service center? I'm trying to decide if I want to do that while it's still under warranty vs. replacing the fan myself with a better quality.
Also, has anyone ordered the power connector for the fan? If I decide to do it myself, I'll probably go with the Orion fan and would like to avoid cutting the connector off the original fan in the event I need to send the entire unit back for some other reason while still under warranty. I read elsewhere where it might be a PH2.0-2P. I can't find a good source for getting this connector (or pigtail) in the US and may order another fan specifically for a Tivo (presumably not as good as the Orion) just to get the connector unless someone has a good source for the PH2.0-2P (if that is what it is). I fund a few options, but after shipping it'll probably be cheaper to just get another entire fan.
Thanks in advance. This is my first Tivo. The unit works great but the hardware is a huge disappointment.
Here's what I'm doing. I just bought two fans since 6 weeks after buying the Roamio OTA at the BF sale the fan became very loud. I have three other basic Roamio boxes and none have a loud fan. One has a date of 13 Sep 2013. I'm going to take the box apart to see if it's the fan or the circuit that tells the fan to run at a specific speed. Why? Because the MBT on all my old boxes is from 37C to 41C. The noisy unit is 33C. If it's not the fan I may have to go to plan b and drive the fan externally. If either of the fans I bought work ok, then I can conclude something is wrong with the new stuff. I'll know next week.
My Roamio OTA was manufactured 31-Jul-17. The MBT Internal Temperature is presently 36 in a room that's about 19 C (66 F). It might be slightly warmer on the shelf where it's sitting, but not much (it's not fully enclosed). The room temperature varies from 15-20 C since I bought the Tivo.
Looking forward to your results next week. What fans did you purchase?
The Mouser and this one from Amazon -> https://www.amazon.com/gp/product/B00LRTQBLA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I had an older DVR (Sony DHG) and replaced the fans. They were 120mm, so they could really make noise.
36C in a 66F room is normal. My quiet Roamio starts the day at 36C in a 68F room. I also have my TiVo boxes on 1/2 feet, which is good for 1C. BTW, one basic Roamio has a 1TB drive, another has a 3TB drive and is a bit warmer.
Also, I have two Mini boxes with a very quiet fan on top. Probably not needed, but each has its wireless bridge on top. So they have a MBT of 33C. With no fan it's 50C or higher. But that's a Mini.
I just did the job using the Amazon fan. It already has the connector which, while different, as is the fan, fit perfectly. The OEM fan is five blades also - the new one seven blades.
It's warming up now. Want tips?
update: MBT has stabilized at 37C. Quiet as a ....
Thanks for the update. So the connector on the Amazon fan works okay so that you didn't have to cut off and reuse the connector from the original fan wires?
Glad to hear its working. Can you tell yet if the system board is properly controlling the fan RPM? 37 MBT sounds about where it should be, correct?
I'll probably order the same two fans . Looks like I can get the Orion fan through Amazon also, a bit more expensive but will get me free shipping on the Evercool one, probably making the overall price about the same.
So far my Roamio is only slightly louder than it was the first three weeks, but I"m expecting that to decline.
Connector worked. Like I said, this is not an identical fan. But it works and the connector fits. My other Roamio, only 2 feet away and also 1TB is the same MBT. Only minor issue is the long wires. But even though it's an OTA, I had a cable card bracket installed. Removing that was required. I would do it first and watch those tiny screws. Since I have replaced the hard drives, I have all three Torx drivers. I would not attempt this job without the right tools.
I'd post the part number of the old fan, but my Chinese is a bit rusty.
Hi guys! New to the forum but not to fans, lol. My name is Gary, and I'm the guy (The Fan Van) selling the Evercool "Tivo" fan on Amazon. (I also have the same fan listed as a Fan Van brand Tivo fan.) I've been working with my distributors to try to get these fans manufactured with the 2 pin mini molex connector like the original, (the Evercool fan has a PH2.0-2P connector, which works but is a little different from the oem fan) but the issue at the moment is Evercool wants a MOQ of 5000 fans to do a connector change, and my other distributor (Dynatron/Top Motor) will do a smaller MOQ but they're not tooled up to do a 35mm fan. I am, however, having them make me the 50mm fan for the Roamio Plus and Pro with the correct connector. It's going to be a quieter fan than the original with a longer life span. By the way, don't waste your time with the GDStime 35mm fan, it's garbage.
You are right, they last the most 6 months then get very loud.
You should sell them @ frys also. They only sell 30mm &40mm, no 35
I am seeing some mixed reviews on the Evercool on Amazon, but for the price, it is a bargain if you don't mind changing them out.
I've sold hundreds of these in the last 2.5 years, so far they have proven to be very reliable. I've toyed with the idea of doing a connector change in-house, but it would be very time consuming (I would have to splice, solder and shrink wrap each one) and most who have used one seem to have no real issues with the connector that's on there.
No issues with the connector. I wish it included silicon mounts. When I installed it, I only used the top two screws. What can I say: it works.
I gave it 5 stars on Amazon.
This is my fourth Roamio going back to 2013. This one was built in 2017. It got noisy after 6 weeks. [no comments needed]
The main reason I joined this forum is I'd like to get involved in trying to find good cooling solutions for all the different Tivo models and be eventually be able to offer them up for reasonable prices. I'd like to provide some sample fans in exchange for some honest reviews. As far as the Roamio and Roamio OTA, the little Evercool 35mm x 10mm fan and the Fan Van branded one (same fan, different label) are going to be the ones I'm going to carry due to their track record and popularity. I'm having some 50mm x 20mm quiet dual ball bearing fans (2 Ball Bearing, 12V, 3700 rpm, 0.10a, 1.20w, 10.90cfm, 2.90mm/H2O, 24.30dBA) that I think will be a good fan for the Premiere, Pro and Plus Series and probably the Bolts also. There's also a 70mm x 25mm fan they used in the raised grill Tivos and other DVR's that I'm trying fins a good solution for.
[QUOTE=" I wish it included silicon mounts. When I installed it, I only used the top two screws. What can I say: it works.
I have the silicon fan mounting grommets I include with Dell fans - they have bigger holes, but maybe they'll fit. I'll go out to the shop and see. That would be a great thing to include, they work good at keeping down noise from vibrations.

Not even close. Bummer. I'll have to ask my distributor, I don't recall seeing smaller fan mounting grommets. Do any of you guys know which ones fit or what they look like?
I found grommets that work, they're the long ones, and you really have to tug on 'em to the point where you think they're going to snap but they eventually pop into place.
