    ...I prefer air cooling as well.  Less to  go wrong.  Been using the same CPU cooler I originally installed. when I built the system  I only needed to replace the fan that burned out.

    You never described your cooling system. How are you cooling down your CPU, and you never mentioned anything about temperatures, are you monitoring them, what do they say.  It's easy to throw a lot of power at something, but excessive heat needs to be drawn off too.

    And there are similar problems with other graphics cards and liquid coolers for CPUs.  Over time the fluid chemically reacts with itself or the enclosing chamber or sealing goo or gaskets to produce debris that clogs up the tiny channels in the cooling block.  The more I hear about liquid CPU coolers, the more I'm glad I never swam in that ocean.

    Just bad design and choice of materials I think, it should be possible to design something that works.  It may be expensive though, but that's usually the "issue" with quality stuff, and why some make cheaper low quality stuff in order to sell more.

    Yeah, that was sort of my point.  At the beginning the systems were simpler and the fluid channels may not have been so easily clogged.  Then technology and research produced better fluids as the fluid channels got smaller, and more engineering aspects grabbed for every little erg of energy to extract.  Then I suspect that someone marketed a "better" (read that as "cheaper" or "yet unproven") fluid and succeeded in selling to some markets because some executive needed a new boat.  Not enough long term, high heat research before selling.

    Ah yes!  The cooling factor.  AMD is currently scrambling to warrantee replace some of their graphics cards that are exhibiting serious and rapid overheating because of debris in the cooling fluid.  Here's the most recent video about it (last article; 12:29 "AMD admits faulty vapor chamber causes RX-7900 XTX throttling")

    Vaper chambers are becoming more common. Nvidia has been using them for several generations now on their Founders models. Turing had them back in 2018, as did Ampere, and of course Lovelace continues that trend. 

    But they require very precise manufacturing, and the XTX is showing us just how important that is. This was probably just a silly mistake in manufacturing, and should get corrected. It will be fine...eventually. They should be able to figure out if this is a bad batch, and pin point who bought them.

    On the flip side I am not a big water block fan. Just the idea of having tubes of water girgling in my PC and potentially leaking is not something that sounds appealing to me. But it is fine that people like them, I am just paranoid. A vaper chamber will never leak and never needs maintenance. The FE cards are so quiet that they pretty much negate one of the main reasons to water cool, noise, and they are pretty cool as well. My little 3060 is a lot louder than my 3090, and runs hotter because of its dinky little cooler, even though it uses so much less energy.

    Hello Daz Studio friends.

    I also got an RTX4090 in a massive case and no heating problems. My Daz Studio program self is the problem. In the pre-calculation of each scene or each 800x800 frame of an animation it looks like DS kind of hanging for a vew seconds and then start rendering. My Monster PC is like 4 months old and running butter smooth on everything except the scene pre-calculation is a bit pain in the @ss last 2 weeks.

    Any idea how to solve it? Yes I got the latest drivers, enough ram etcetera.

    When you render the animation, do you just run the image sequence? If so, it's loading everything every frame. First render one frame as a still image, doesn't have to be to a 100% completion, as long as something is loaded and rendering, and do not X out that window, leave it open. Now change to image sequence and render the animation. Everything stays loaded in the system and you won't have that wait time between each frame for it to reload everything. I read that somewhere else in the forums here a couple years ago and it's saved me soooooo much time!

    I have only 1 character and a backdrop in the scene. I always use a simple turntable animation and 2 lights. I always used this setup. When I started rendering turntable animations everything goes very smooth but now its like Daz needs more time to pre-calculate every frame of an animation. Normaly it cost me an hour but now i need 4 hours for the same type of animation with same length. I render in image sequense indeed.
