IceGiant ProSiphon Elite is a 2kg air cooler with quad 120mm fans

[HEXUS]

It uses the 'thermosiphon effect' to chill your mainstream or HEDT PC CPU.

Just be wary in a vertical position of it straight up ripping your motherboard out!

I remember an old Arctic Cooler jobby that was quite heavy tore off an AM3 bracket when it was being transported once!

Reminds me of the Vapochill Micro CPU cooler I had years ago. Loved that cooler.

Used a similar principle with a gas but that one was picky about the install orientation and was not anywhere near as big.

Weren't they supposed to reduce weight/size before releasing to retail? Anyway, must be great for Rocket Lake.

Can't think why I should want to risk motherboard damage with this monster, rather than use a 280mm AIO.

It's likely more effective than an AIO. Most AIOs can't beat top end air coolers. Custom loops are a different matter but AIOs are mostly about looks and quiet. Aluminium rads are not a sign that serious cooling power is a primary consideration (more like cheaper transportation costs).

EDIT - also they have reduced the size a bit. Also, it is picky about orientation. You have a choice of two but you must get it the right way up which ever you choose. It's great for Threadripper without needing an AIO but, as it is designed for multiple chiplets and a large heat generating surface, it isn't as good as existing coolers for more traditional consumer grade chips. For Threadripper, this is far better an AIOs and is within sniffing distance of custom loops at a way lower cost.

AIO here for my main systems because I do videos and record audio so the almost silence is a boon to me...

Aye, I do like my AIO for that. It's 6 years+ old now and I'm awaiting pump failure (I've set low temperature and RPM alarm thresholds). I'm torn between a "proper" AIO with a copper rad and custom loop parts (therefore expandable and serviceable) and just a really good air cooler. With a 3900X I think this sort of thing would be utterly wasted on me but there are some very good air coolers at 1/2-1/3 of the price of the AIO I'm considering. For my use, performance is comparable. The nerd in me loves going to excess and it's hard to quiet him down.

Only a 2700X in work pc and a 3600 in music pc but the AIO's work even less because of that. The AMD setup with air coolers still seem to do that ramp up and down wildly sometimes despite my best efforts to calm them down....

I had the exact same ramping wildly with AMD on my AIO. There was some smart fan thing which was trying to react to very sudden changes in temperatures. I ended up turning off smart fan and setting fixed fan speeds at certain temperature thresholds. So up to 50C it's at something like 40% fan, ramping up to 70% at 60C and 100% at 70C. The CPU temp never exceeds 75C and I've seen no weird throttling behaviour as a result of doing this. Drove me insane. The fan thing was part of the Gigabyte Aurous mobo software.

I was thinking in terms of a roughly price comparable alternative. I actually use a Be Quiet! Dark Rock Pro 4 which runs nice and cool and, damn near silent. I don't let water inside my PC.
