Hello,
I have tried to do immersion cooling with two of my miners. However it didn't went well. I would like like to open my miners and remove the oil if that is possible, so the miners can work again with air.
Do you have any idea how should I clean the oil? If I dive them in water with soap and let them dry very well would make sense or it will damage my boards? If I simple clean them with paper?
Thank you in advance.

I'd buy a can or two of "flux cleaner" since it'll clean and is made for spraying on pcb's. Soap and water? Not so much...  |

These aren't the Droids you're looking for: S5 & S7 (Sold), R4B2, R4B4 (RIP), 2x S9 obsolete, 2xS15-28, S17-56, S17-70

After searching the term flux cleaner, which I wasn't familiar with those type of products, I found that those are in two categories. One that need an ultrasonic cleaner machine according to the Youtube videos and I have found also similar product called Vigon EFM . Do you think this is safe to use? https://www.zestron.com/en/vigon-efm.html |

Not exactly ultrasonic. I meant aerosol spray can that you spray on and it cleans/evaporates away to cleanliness such as the Vigon EFM you referenced, yes.

I'd probably use dish soap, rinse with distilled water, then immediately dry them off with compressed air. Flux cleaner is made to remove flux, I'm not sure it will do a good job at dissolving oil.
|
Have some dead Bitmain 17 series hashboards or full miners?
I'll buy them ... send me a PM with what you have and I'll make you an offer! |

Q-tips and alcohol? |

flux remover has solvent in it. Solvent cleans oil.

I'd say dish soap and distilled water followed by a spray of 95% isopropyl alcohol. Don't immerse the thing in the water unless you also plan to immerse it in isopropyl. In fact, don't immerse it, just clean with a brush then Q tips, then isopropyl. Then dry for a day or two before firing up.
I've had to clean some pretty filthy miner boards in my repair adventures, most were doable with alcohol and Q tips, but a few total pigs (as in they were run in a pig barn) got the soap and proverbial fire hose outside the lab first.
(I think I posted a picture of one of those at some point)

Well guys thank you very much for your support and your ideas. I guess I will do both, to be sure that I have done everything and if they do not work then it should be hardware failure and those miners need to go... I have found also on amazon this kind of spray which is way cheaper. Do you think this might do the work also? https://www.amazon.co.uk/WD40D-N-A-Contact-Cleaner/dp/B006UCJ5WQLightfoot you mention specifically to don't immerse the whole thing in the distilled water with soap, only if I plan to immerse it also in isopropyl. Why is that? Due of moisture or something else? I ask because I opened the miners and it is huge pain to remove the dust. The dust with the oil became so sticky and you can't remove it easily with Qtips. Also tried yesterday with Qtips and paper but if try to remove it small fibers remain within the board since it is sticky the whole thing due of the oil. |

Water only harms electronics while they are on and it's not the water that causes problems its the salts / minerals in the water. If you clean the boards with pure water and let them dry they will be fine. Using ISO after a water bath just helps get excess water and minerals off the board plus it has a low boil off temperature and will all evaporate at room temp.

The things I worry about with immersion in distilled water are chokes and electrolytic capacitors. What kind of miner board is this; Antminer S9 or something else? Pics?

I have heard the same that mineral water can not damage the board. However I am not sure and better be safe than sorry  Thank you for your input. |

I would be careful with water water: The problem is if there are minerals in it and it evaporates off you can wind up with gunkies or shorts under the hashing chips or on the pins. QFN chips have *very* close pins and BGA is even more annoying, thus why I recommend rinsing with isopropyl alcohol.
The fact that your board is covered in greasy goo means that you probably don't have a whole lot to lose by hitting it with a garden hose and soap. Pressure washer may be a bit much, maybe I should bury an S9 board in the mud for a month, then dig it up, take it to the car wash, and see what the worst case scenario might entail....
What's the worst that can happen :-) (Note: If this is a S17 don't do this)

guys hello, the only spray that I can find local is the WD 40 https://www.amazon.co.uk/WD40D-N-A-Contact-Cleaner/dp/B006UCJ5WQBecause it doesn't have the title flux remover spray, and is 5 times cheaper than the others, do you believe that is can do the job? Thank you. |

According to the manufactures video and reviews on amazon it looks pretty safe to use on electronics, check out the reviews on amazon and you will see people using this on computers and other electrical components. I think for that price it worth giving it a shot https://youtu.be/-qTMK7SpfYk |

I've never used it, but it will probably work. Try it on one board and see if it cleans up and/or damages anything.

Thank you guys for your time and your answer. I have ordered it. I will inform you how it will go. |
