I've got 3 Samsung tv's, 2 of which have/had the tab bond problem. Seems the internal heat is a big contributor to it, and although the damage may be done I'd like to do what I can to prevent further/future damage. I'd like to mount a couple small, say 40mm 12v computer style silent fans in each, up near the top vents, to pull the hot air out, but I'm not sure where to tie in the power. I know there's a 12v hookup on the plug in connectors, but would they handle the minimal, yet additional load of the fans? Is there a better place to tap into them?
Heat dissipation ?

Re: Heat dissipation ?
The main power board inside the tv will have a 12v rail that will have enough current to power the fans fine, are you planning on installing them inside or outside of the tv ?Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Re: Heat dissipation ?
Btw great idea while people dont see it but passively cooled lcds and plasmas are slowly cooking them selves to death, installing fans is a great idea the only lcd I have seen with fans is a 32" sharp but most plasmas I see have fans....Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Re: Heat dissipation ?
I planned on mounting them inside the tv, maybe on the rear housing vents themselves. Several years ago I had a heating issue inside the compartment on our entertainment center. I took an old computer power supply case, mounted a fan inside and powered it with an old 12v accessory transformer, and plugged it into the "switched" post on the receiver. Set it to blow between the receiver and the dvd player. It worked like a charm, so I figured this might help here too.
I'll check my "spare parts bin" for fans, or get some new ones on the way. Thanks for the reply.Comment

Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

by emil_tHello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....04-12-2024, 06:54 AM

Hello, I have a System76 Gazelle laptop (model gaze14) which now only partially powers on and does not boot properly.
History:
This laptop has served me well for a few years. It's always been a bit noisy with the fans and recently became much more so on both fans, where just opening a vim/notepad session would cause the fans to spin up loudly and make a grating sound, like the ball bearing were mechanically wearing out. So after blowing the dust out of the fans out didn't help, I ordered replacement fans and heat sink component from System76 which were sold... -
by defame5Hey all, I've been trying to fix a rx570 XFX XXX edition 8gb. Keep in mind I've no knowledge so I've been doing this solely using tutorials. Any help is appreciated.
8pin connector led is open when pc boots, but nothing else happens (no image).
Fans don't spin. Before the gpu broke completely, the fans used to spin at max rpm at the start and there were some wonky things happening in general, so it was probably defective already.
Everything below is based on this video: https://youtu.be/2Yz7HfzggYc?si=UM8VOndmqJX1gfgJ
PCIe pins are all ok. They have similar... -
