Re: Cap Identification please.
I am not exactly sure what is reasonably high mass tip, but I use 2.5mm^2 solid copper wire for my 150VA gun.Less jewellery, more gold into electrotech industry!

Re: Cap Identification please.
I don't think its vrm out, so I would not risk 2.5v.
the 3.0 version of the board had the cap as a real polymer there, I think its a reg cap for that chip up there
the output vrm is lytics

Re: Cap Identification please.
The image in that URL shows wet electrolytics, not polymers. Those are sleeveless Panasonic FL without a vent stamp. Behemot dissected some 6+ years ago.
The font on the failed 680uF 4V capacitors reminds me of Suncon (formerly Sanyo's electrolytic division). The font and vent stamp are both a match.Comment

Re: Cap Identification please.
Seems like these custom short caps were quite common for a time of the 775 era. Always around the socket, under heatsink.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Would anyone know what this component may be? It's on an ASROCK B460 Steel Legend Gaming PC Motherboard. The writing on it is 29 7B / 43N.
Thanks.... -
I have peltir element glued to heatsink with something thick and sticky like putty... it cant be separate with force or heat without risk of breaking ceramic or damaged semiconductor layers due to force (eg if try twisted, pulled, lifted)... method that I am using is a single thread for needle (thin and firm thread of pure polyester that cant break with bare hands without glowes), and using it like a saw between heatsink and peltir. I holding a heatsink with knee against table. It slowly cut throug putty and release glued parts. It is slow proces, but preserve undamaged component and heatsink....

Hello everyone,
I'm looking to upgrade the heatsink on the main processor of my TV's motherboard for better cooling performance.
The current heatsink is a square-shaped one (2.8cm x 2.8cn) with a basic design, and I believe a more efficient heatsink could help with thermal management and potentially extend the life of the TV.
I'd appreciate any advice on the best type of heatsink to use, specific product recommendations, and tips for installation.
If you've done a similar upgrade, I'd love to hear about your experience and any challenges you... -
Hi guys,
I managed to semi-kill an ASRock N100M board after updating Bios from 1.10 to 2.01. It's a zombie now, dead, but not dead.
ASRock N100M special features:
- CPU soldered to board, small Intel 12th gen
- iGPU
- four POST LEDs
Problem after updating Bios to 2.01 using the in-Bios update tool: no picture, no boot.
I am not sure anymore if it booted at least once successfully after updating the bios to 2.01, maybe not, I can't remember. I think it did not.
Symptoms:
- no picture/signal on any of the display connectors,... -
I have an AsRock Taichi 7900xtx, and the minimum fan speed is way too high at 1000rpm, and thats with it's Quiet BIOS switch on, and me setting the fan profile as low as it goes, while on.
Now 1 thing I could do is just make some circuit to put in between the fan the the GPU, and leave the fan on all the time, but anytime the GPU is sending the PWM for min speed, I'll just send something lower and quieter.
But does anyone know what how AsRock usually sends the PWM to the fans on GPUs and mobo's? Is it from the MCU that's often near the 12V inputs and fan jack ? Or is...
