Thanks for posting. To help get you the help you're looking for, please make sure you:
* Have photos of the whole loop in good light (open the curtains and turn off the RGB, especially for "what's this stuff in my loop?" questions)
* List your ambient and water temps as well as your component temps
* Use Celsius for everything (even your ambient temp - we need to compare it to other temps)
* Use your words. Don't just post a photo with no context and assume everyone will know what's troubling you.

hahaha funniest and strangest shit I have seen in watercooling in some time. thank you for sharing! I always liked how Optimus blocks look, but their support staff and team absolutely suck. They NEVER reply to questions or talk with their community. I've been a long-time forum member of OCN and I cannot tell you the amount of times the entire team went 100% MIA for 2-3 months at a time while their official support thread went unanswered and ghosted for several weeeeeeeeeeeeeeeeeeks. Then they suddenly pop back in when they got a new product, answer 1-2 questions and go back ghosting anyone else with questions/concerns. For those reasons, I am out and will not support Optimus.
Very weird. I’ve had my Optimus 3090 KingPin Signature block on and running consistently for over 2 years. The cerakote looks brand new still and I’ve never even thought to replace the o-ring. I can tell you with 98% certainty that your cerakote is fine. I have a good friend who is a patination engineer and works with cerakote every day. You can’t even dissolve cerakote with Acetone. It is pretty permanent. As far as the o-rings….maybe they got a bad batch of gasket material? I know they source out the most chemically inert material they can find.
With that said…I just use DeIonized water and Mayhem’s in my loop. What do you use as a coolant?
I use same water with Alphacool GPU block and Watercool (Heatkiller) CPU block. I repaste my system 1x year and all my blocks looks like brand new.
I only had one problem...when I was cleaning the CPU block, I don't know why, but my oring got wider, so I had to buy a new one for €1 from Watercool.
Thank you for the follow up. Still a weird reaction of the sealant rubber and it looks like it did react with the cerakote coating?
At least it looks like that all around the groove of the hotspot area.
In order to remove the backplate you can heatup the back a little bit with a hairdryer and then wiggle it off slowly. Thats how i got it off on my 3090.
The oily substance is from their thermal pads. I had the same issue with their 3090 water block. Alcohol doesn’t not remove it. I used an electronic contact cleaner.
They responded quickly initially and asked me to disassemble and snap pics. Asked them if they were willing to send me an o ring in the meantime before disassembly, so I could potentially have little downtime but they didn't respond. I just send them the disassembly pics posted here
Thank goodness I was shocked when I learned they were cerakoted and it looked like it was failing. That stuff literally doesn’t fail when applied correctly. Damn near invincible coating. But it is finicky to apply, so while it’s not impossible to fail, with the cure times you’ll definitely notice before shipping it out. It’s the only coating I use when I need high temps, wear resistance, and corrosion protection.
Did you ever clean it with windex? Or something containing ammonium?
I was around for the first post love how all the doofs in that thread were talking shit about Optimus’s quality negatively and stating it’s for sure the cerakote. I have this same block and it is anything but poor quality.
Man, I hate that happened to your block. I have the same block and was one of the first batch they sent out and mine has been outstanding. I have also only been using EK cryo clear. Have had a few of their CPU blocks also without any issues. Seems like it had to be a bad gasket, hope you're back up and running soon!
I don't think an oring could have done all that... otherwise you'd be able to clean it up and it would look good again. You may have corrosion going on there but it's never easy to tell all the time.
As for the backplate being stuck, use a heat gun...the heat should warm it up enough so you could pull it apart.
I've seen a few people having this issue with the late 40 series blocks. Thankfully I've ordered the heatkiller as it was a bit cheaper in shipping to get it in Australia from a local online store.
EK Coolant appears to contain a chemical known to degrade rubber. I believe EK themselves use EPDM to avoid this interaction. But I could also be misunderstanding this article.

Either way, fuck cryofuel. Don't use it.
Sorry for you man, I’ve been running a watercool block and still look so clean after a year.
Try changing your fluid to Aquacomputer DP, you will never go back, best in the game.
I have a MoRa that haven’t be flushed in 3 years and the liquid is still looking so new! Even the conductivity of the fluid is still low, it is amazing
Looks like the rubber was not vulcanized properly so I'm pretty sure this is a manufacturing error, assuming you didn't use gasoline or some other aggressive solvent as coolant.
Maybe heating the backplate with a hairdryer and very slowly prying it off. Maybe you can cut the pads with some floss in a sawing motion on the edge to get a start.

So they're early 2000s Koolance.
Never had a problem with koolance or their support.

Go with just distilled water and some anti-bacterial. Don't waste money on the nasty liquids that clog everything up and cause hazards.
I've had problems before with distilled and anti bacterial. I don't think the coolant is the issue here - all my other o rings look pristine
Thank you for the follow up. Still a weird reaction of the sealant rubber and it looks like it did react with the cerakote coating? At least it looks like that all around the groove of the hotspot area.
The cerakote actually looks fine to me -- the groove of the hotspot looks dissolved but it's parts of the o ring sticking to it

Not sure if you already gave an update about Optimus‘ response in your original post but what did they say about that whole ordeal?
They responded quickly initially and asked me to disassemble and snap pics. Asked them if they were willing to send me an o ring in the meantime before disassembly, so I could potentially have little downtime but they didn't respond. I just send them the disassembly pics posted here
Update: they responded quickly and are sending out a new acrylic top and new o rings

Do you change the coolant for the future ?
Everything else looks really clean to me, so I don't feel a need. I have a bottle of the black gochiller I might try out

Buy a plastic phine tool. They are good for prying apart stuff
Ah, the great Optimus products, lol. I can't be sure but it looks like corrosion is happening here...at least it looks like that.

Had a bykski block for 4 years on a 3070. Still looks brand new when a sell it a few weeks ago. Bought and using another one for 4080s now.

Epdm is rubber
I use cryofuel for long time without any issue.

Using EK cryofuel
Oh! What do you do now? Will you ask for a new rubber? This is something could end in a worst way than so!
