    Eh? they always made high vis, stickers, and adhesives. That's been their bread and butter since the beginning. They only got into the disk biz because they were developing the chemicals used on the disks.

    boiling point depends on the specific Novec fluid used.

    7000 - 34c
    649 - 49c
    7100 - 61c
    7200 - 76c

    Laugh it up, but I literally spent $593.98 for just the fittings in my current machine.

    Flourinert has some substantial issues with these types of applications including decomposition into highly toxic chemicals not to mention the ozone and global warming issues with it. Novec is a much refined application of the concept behind Flourinert. There were issues that developed with long term use in the Cray-2 where it decomposed into Perfluoroisobutene which is incredibly toxic (Its literally a schedule 2 chemical weapon and 10 times more toxic than phosgene gas and a boiling point of 7c)

    You can do this with $20 worth of vegetable oil. Just seal the box, pray nothing stops working and never open it...

    Made that mistake 12 something years ago...

    Was the last vegetable cooled PC allowed in the house.

    I've read up on this. Even with a "perfectly" sealed box it'll travel through any cables and get everywhere!

    Eh? Their other products never appeared here in Europe until recently. Literally the only product you could see were the floppies in the nineties. And there was no wikipedia back then to check up on a company. So how could we know anything about it apart from them making disks?

    3M, GE and IBM have historically been diverse companies. IBM used to make adding machines, clocks and meat slicers.

    As far as Novec goes, I can see myself making a big mess with it. The only advantage I can see is that I wouldn't accidentally spill water into the top fans (like I've done with two of my computers - one survived, one didn't).

    Not only that the constant heat cycles on something organic does not smell well. Especially when you open the sealed container inside your house after 7 months of no issues, it went from a quick fix to my wife yelling at me to get that out of the computer room.

    Pulled everything out hosed it off, then put it in a hot shower for 30 something minutes. After letting it dry for a few days everything worked, well almost everything had to replace the GPU fan. Other than that it worked fine.

    I really love seeing all these stories about people doing extreme things with cooling CPU's but as a gamer and experiencing that many gaming issues are GPU bound I'd love to see more with GPU's. Just trying to imagine either team red or green's best holding 25-35c and the cores screaming and vram clocked ridiculously high. I'm sure it's being done but surprisingly a challenge to find those kinds of stories in recent years. I think I saw one or two for the 1080TI. Don't get me wrong, it's awesome seeing how far we can go with a CPU but let's not forget about the other heater in that box.

    edit: A little more clarity on that 1080TI reference. I think I saw a story about LN2 with one hitting like 2.5~2.7Ghz or some such. I'm curious about Novec or FLourinert uses with them or even RTX, VII, Vega64.

    The whole point is yes, they did stuff like this in the past with Flourinert, but there are significant reason why it is no longer a viable product to use for these types of things, the Cray-2 issues being a case in point.

    Bro his CPU is boiling liquid... This needs to happen in 99.9999% of pc's.

    BTW, the person who did this has posted the first six months of the construction of this. Sadly after watching it for over 1 hour I found out that the final few steps (where the actual Novec fluid is added) were not posted. With that said I don't think he is using a vacuum. He does have a rubber pad above the glass but did not appear to seal around the holes enough to hold a vacuum. Also he mentions that some of the Novec gas will be lost so he will use the metal pipes sticking out of the top to add fluid when needed.

    I'm not laughing at all. The stupid price of fitting is the only reason I didn't switch to rigid tubing in my last build. Didn't have the stomach to drop another $500+ on fittings when I have something along the lines of $1,000 worth in fittings laying around from previous builds...

    That is like saying "its amazing look I have put radial tires on a car/trailer/motorcycle....its new!" When bias ply are already there.

    No to use your analogy it is: hey we used to have these great tires that did a lot of cool stuff but caused people to die due to the VX nerve off gassing, we now have a new solution that does all that great stuff that doesn't kill people.

    Yes, and before we had GPUs with thousands of cores, we had slide rules. Before we had slide rules, we had the abacus. Before we had the abacus, we had 10 fingers.

    Therefore, nothing related to computing can be noteworthy or interesting because we used to count on our fingers.

    I don't think you want to operate in an environment where you're getting liquid/vapor phase change in vegetable oil (nor the inert atmosphere needed to not get ignition). ;) That's an apples to chainsaws analogy, where beyond the association with "trees", everything else falls apart.

    No, it's like saying "look i have developed this thing that will produce a graphical output with a thousand cores...it is totally new" when GPUs with 999 cores already exist. Demonstrating something your company has been doing and selling for 30 some odd years isn't novel.

    I asked what Novec fluid was used and got back this:
