Alphacool Eiswolf 2 for rtx 3090

[globbert]

Anybody got personal experience with one or know of a high quality review with quality analysis of the product? slightly intrigued by it for an easy way to water cool my 3090 and get rid of the fans that whine pretty aggressively but i havent been able to find a review by a more reputable reviewer with decent production quality.

This sounds like an AIO.  AIOs have fans too they’re just on the water-air radiator.  They’ll be 25mm thick though whereas the ones on a video card are generally much thinner.  My personal move is often to simply remove the shroud from the video card and zip tie some case fans to the now bare aluminum air radiator.  This often makes things a good bit quieter though it makes the video card thicker and uglier.

Have one rn its good I did change the fans day one cuz the alphacool ones were too loud. I do have a 80mm fan pointing on the back to make sure thr vram is cold

 

I did add it to a reservoir I had for easier maintenance.

sure it will have fans but instead of 2800rpm 80mm fans that are super obnoxious it will have 2 or 3 (depending on radiator choice) super quiet high static pressure noctua fans becasue i put noctuas on everything. Like if this were my old rig i'd maybe humor the case fans on the card method but i've got too much into making this a clean setupto halfass it now.

yeah i'd intend on swapping fans right away. what kind of temps and clock speeds are you getting?

Who’s got 80mm fans? I generally do that with 120s.  I haven’t even seen an 80mm fan in years.  For half height cards maybe?  I haven’t seen a video card that could take a 140 yet, and for a few they would probably prefer 100s (which you can get) but 80’s?  I don’t buy noctua a at all.  Sure they’re great fans, but they’re soooo pricey. I’d spend maybe $6-12/fan.  Not $30.  Iirc most of my fans are silenx they’re all old though.  I understand the fan to buy right now is arctic cooling.  That stuff changes like the weather though. Can’t counter the 1/2ass comment.  I’m all about the half ass solution.  2.0 and go computing from me.

Basically max boost and 65c with the 360mm. Keep in mind my fans are running at like 600rpm max because I want NO noise what so ever. The pc is more silent than ambient noise.

This tracks.  You can probably do 8 or 900 rpm and get away with it with 120s. Less with 140s It’s when you get above 1000 with 120s that things start to get loud.  80s will have a higher number before that starts to happen.  Something about the velocity of the blade tip.  It’s effectively faster with bigger fans because the blades are longer.  Bigger wheels. Maybe something about the speed of sound? Seems far fetched. Sonic speed varies a lot but tends to be somewhat near 600mph which is pretty dang fast. I may not be remembering that one right. That’s the whole point of dual fan air coolers.  2 slow fans are quieter than one fast one sometimes.  Not all the time, but sometimes. What I don’t get is people putting 6 fans on a radiator.

the zotac 3090 i got, and my bad they're 87mm not 80. i thought about 3d printing a shroud another guy designed to fit 3x 92mm fans but for that level of effort i'd rather look at something more refined. I'm usually totally down to halfass stuff but i really want to keep this all neat and tidy.

thats absolutely beautiful. 

 

 

thank you both gentlemen i think im pretty comfortable going with the eiswolf 2 but i'll probably just make sure im not missing any other/better options before jumping on it

Fyi with the eiswolf the back is still just passively cooled so I slapped an ancient antec 80mm fan on there, made it run at 3v and it droped mem temps from around 85c to 60c ish. Put a lego brick at one end and the other end is doublesided taped to the card :p.

 

This isnt needed and will be better if I increase airflow in my case but I dont want to.

i think i'd run it to see where temps fell, my case should have tons of airflow so im hoping the passive back isnt a huge deal. Full time i'm a machinist so im humoring the idea of a one-off copper backplate with tons of fins and surface area to take advantage of the 7 140mm case fans but i think i'll at least test the stock backplate with some better thermal pads first. I definitely could see the benefit to a backplate fan for sure and might go that route but i've tried so hard to avoid having any small fans in the rig (almost excusively for noise reasons) so i'm not sure i want to go that route if i can avoid it.

If it’s about noise and there’s room if you have any heat sinks around you could see if doing that would still do it passively and that’s one fan down.  Probably wouldn’t be worth buying any, but they won’t make the thing warmer.  Or shouldn’t anyway.  

The OP apparently has aesthetics issues (no judgement) so unless the thing is mounted vertically they’d show on his rig.  They don’t have to sit in the middle though,  and they don’t even have to be shaped like heat sinks.  Basically anything metal with a flat bottom.  You could display a little sculpture in there that just happens to be metal (ideally copper, aluminum or brass) has a lot of surface area, and has a flat bottom.  Doesn’t even need heat tape.  It’s literally sitting there so paste would work great.  Better than tape even.

Oh the stock config is totally fine if you have decent airflow. I just dont since myfans barely run

Just said it in another comment but its fine at stock with decent airflow. I dont have this due to my fans running slow as possible.

So it’s about noise.

Yes thats what I said in my first post about the 65c mark. I can get it to 50 if I want to turn up my fans to like 32dba.

But there’s no need.  I get it.  It’s just a “the fewer fans the better” kind of thing.  Might not even work either.

I'm sorry I lost you. I just have arctic p12's on my 360 eiswolf 2 running at 620rpm in a bequiet 500dx with a ryzen 3900x (currently not in the loop) and it's working nice and quietly.

Multiple fans make more noise than single fans except when they don’t. A second fan generally only adds 20% or less to the equation. If that 20% takes it below critical rpm though even though there are two motors going the total noise is lower.  So ideally one wants as few fans as possible running below that number. Single fans are often quieter than dual fans even if they need to spin faster.
 

In which I ramble on about how I’ve been told hearing works

Spoiler

I’ve found it matters less and less as I age though.  Those little strings that hold the doors on the towers in my inner ear break one by one as my hearing slowly goes.  You may at one time or another hear a sort eeeeeeee in an exceptionally pure tone that starts suddenly and fades away over a minute or two.  That’s the sound of one of those strings breaking.  The shorter more tight thinner ones for higher sound registers generallly break first, which is why those teenager repellant speakers work.  Older people grow deaf at those registers.  
 

The way the amplifier works is it’s this tower with a door at the top that is connected to a string. The whole thing is surrounded by liquid that is some neurotransmitter or something.  So when the string breaks the door gets stuck open and your brain tunes out that tone.  There are a whole lot of them to start.  I want to say tens of thousands but I don’t know.  
It’s apparently a little coiled harp with thousands of microscopic strings, sort of.  I saw an electron micrograph once of the top of a single tower with its string and door.  I just found the whole thing really cool.

My data comes from one friend who developed cookie bite hearing loss from loud machines where he worked, and from an ex-girlfriend who had another friend that had to have implants put in their ears because they suddenly went deaf.  They can make stuff that acts like it but it’s bigger and clunkier.  The ear implant he got had only 128. So he could hear, but would occasionally lose parts of conversations
