Computer tech refurbs GPU clogged with tar and nicotine from 17 years of use by a smoker — 'I am not blowing on that; I’m getting cancer from this' says repair technician
Smoking is bad for your health, and your PC.
A computer technician on YouTube shared their refurbishment process for an Asus 9800GT Matrix GPU that was allegedly used by a smoker. We will see in Madness727’s more than hour-long video how they turned it from a tar and nicotine-clogged relic into a pristine example of the graphics card that runs perfectly in a PC system.
I recently got This ASUS 9800GT MATRIX that was in Abysmal condition from a Smokers home.It was so bad that I decided to make a video going over the Full Refurbishing process.The results are INCREDIBLE!https://t.co/ot6PwgfnPg pic.twitter.com/JVYEoZ8hGPNovember 8, 2025
The Asus ROG Matrix 9800 GT hit the market in 2008 and was a premium mid-range GPU built for enthusiasts. However, after around 17 years of use without any maintenance, it’s almost unusable, with the heat sink completely blocked by gunk. The graphics card actually looked relatively clean from the outside, but when the repairer removed the heatsink and opened the card, they discovered that nearly all its surfaces were covered by dirt and grime. The worst accumulation was under the shroud, with Madness727 commenting, “I am not blowing on that; I’m getting cancer from this.”
After disassembling the graphics card, the first thing he did was to clean the main board with degreaser and running water using a toothbrush. They then patted it dry with a towel, after which they used a blower to get the remaining water drops off the board. To further ensure that everything is dry, they also used a heat gun on the core, memory, and VRAM, as well as the heat sink itself.
The fan, heat sinks, and other components went under the faucet as well, with the fan motor being the only thing left out. Instead, they cleaned that part with isopropyl alcohol, after which they applied bike chain lubricant to make it run smoothly and quietly once more.
With everything cleaned and dried, the technician applied new PTM and reassembled the GPU. The final result is quite impressive, given the age of the graphics card. During the cleaning process, Madness727 said, "It looks brand new; no scratches, nothing —which is crazy, by the way. It’s in perfect physical shape; there’s [sic] no dents or scratches, or missing MLCCs or resistors on the PCB. Everything is perfect."

Lastly, they tested the card slotted in an MSI Z390-A Pro motherboard with an Intel Core i5-9600K processor and some Viper RAM sticks. They got the GPU running, with the card pushing out around 16 FPS on their benchmarking software, and about 5 FPS in Crysis. These aren’t playable numbers, but that’s understandable, given the games, settings, and age of the card.
We don’t know where the refurbished Asus ROG Matrix 9800 GT will end up, but the tech mentioned that they have already sold a couple of these GPUs they’ve previously owned to a collector. We’re hoping that this lovingly restored piece of computing history will also get the same treatment. After all, even though it can no longer run the latest games and compete with the best gaming GPUs you can buy today, it still has a unique design that Asus is continuing today with the ROG Matrix RTX 5090 with built-in sag detection.

Lungs clean themselves somewhat, GPUs do notTechieTwo said:Maybe the pic of the uncleaned GPU shows what the owner's lungs look like? :( -
Madness727 Hey! Thanks for sharing my adventure with the 9800GT MATRIX!Reply
To answer your question "where the refurbished Asus ROG Matrix 9800 GT will end up", it's in my hardware collection and it will stay in my collection. I'm happy to own it again and even happier that I could restore it back to it's former glory.
Here it is sitting alongside Some of my collection.

So a fresh layer of tar from 17 years of cancer sticks is the optimal way to preserve that daily-driven computer hardware under the gunk. 🤔Admin said:The final result is quite impressive, given the age of the graphics card.

............ provided the fan keeps moving. -
dakino A lot of this info about how to do this is bad advise..Reply
Do not use a standard degreaser on circuit boards . I have done similar cleaning on circuit boards before, including motherboards. A better cleaner to use would be something like simple green or mean green. These cleaners will almost melt away the cigarette buildup without any scrubbing, but are environmentally friendly and less harsh to the boards themselves.
Use a hair dryer is fine, but heat guns can get hot enough to melt solder causing damage.. Too much heat can also damage capacitors too.. If in doubt, blow the areas out, like in ram slots, under chipsets, etc with compressed air. I got an air compressor to do just this..
One reason air is a better choice to use first.. Whatever cleaner you use on the board, you don't want to leave on there. Compressed air will blow it out of cracks and small places.. Using just a heat gun will only dry that cleaner that may not have been rinsed off in the water to dry and stay in place on the board.. This could, depending on the cleaner cause future damage to the board itself over time. And using a compressor will save you money vs canned air over time too.
Then, if you don't want to heat it up, you could air dry it for multiple days to let it dry.. If it's winter, you could also put it over a heater duct vent to let that warm it up to help dry it..
Either way, heat guns you have to be very careful with using them around circuitry. -

True, but some smoking damage on the lungs are permanent.
My dad passed away when I was 30, I never ever saw him smoking, when he was sick a year before he passed away they did some testing and asked him you smoked before? he told them yes but more than 35 years ago, the doctor said I can see it has been a long time but it's still visible in your lungs, it's already permanent. -

Sorry for your loss, its good advice though. Similarly, aneurysms don't tend to book appointments, they just kind of show up.Amdlova said:I know a guy never drink, never smoke.
