Of the many events we had time to cover while we were at CES 2024 this year, a few things did slip under the radar— among them, a pair of new IceGiant pump-free liquid CPU coolers.

IceGiant has already made waves with its Prosiphon Elite cooler, which costs roughly $170. However, the company is expanding its cooling portfolio with these new Titan series AIO liquid coolers. Unlike conventional AIO liquid coolers, the Titan series doesn't use a pump. IceGiant states these coolers feature an all-copper evaporator and an upgraded six-core 360mm condenser.

The IceGiant Titan 360 supports the Intel LGA115x, LGA1200, LGA1700, LGA1851, LGA2011, and LGA2066 sockets. However, AMD socket support is limited to AM4 and AM5. Similarly, the IceGiant ProSiphon Titan-TR 360 only supports the AMD TR5 socket.

While these costs are easily comparable to custom loop setups, the maintenance involved with those is exponentially higher— and if IceGiant's no-moving-parts-besides-fans philosophy holds up to the test of time, the pump degradation that befalls AIOs and custom loops alike shouldn't ever be an issue, here. If IceGiant's claims of longevity with zero maintenance besides periodically dusting and/or replacing the fans hold, these coolers could make a lot of sense for HEDT builders intent on high-performance, low-maintenance cooling.

The current listings price the IceGiant Titan 360, which is targeted at overclocking modern mainstream platforms, at a whopping $419.99. Meanwhile, the IceGiant ProSiphon Titan-TR 360 keeps the same radiator length but bulks up the design to accommodate the larger Threadripper CPUs, costing a brutal $599.99. These coolers look pretty good, and including a lifetime warranty (six years on the fans) is compelling.

That price point is difficult to justify regardless of the novelty of a pump-free cooler design, though—excellent cooling performance can still be much cheaper with the best coolers nowadays. Before users consider purchasing decisions, we want to see this build's final noise level. The system could get quieter without pump noise, but fans still make noise. If IceGiant can successfully ship the quietest AIO on the market while providing a lifetime warranty and painless maintenance, it could be a real pocket killer.

    As a current user of the Prosiphon on a Threadripper, I can tell you that they are incredible. This is a premium item for those that are going to push cpus really hard, overclock or want an item that lasts a long time (with a great warranty). I am curious what the wattage they can cool will be for these. I only have good things about their past products and am looking forward to the testing of these.

    How sensitive are these things to orientation and temperature range?

    Orientation of their current coolers matters (condenser above the evaporator) and I would suggest it will matter for these as well.
    When you say "temp range", are you referring to ambient, case, or cpu?

    I spoke with IceGiant at CES and they confirmed the cooler can only be mounted horizontally on top. They would need a different SKU entirely for vertical mounts and wasn't on their roadmap.

    But they cool like a monster. They demoed the Threadripper hitting ~850w and they got a new record in y-cruncher 10b while doing it.

    Nice! Impressive!

    In principle sounds great; but my Lian Li O11 Air Mini case only holds 240mm or 280mm radiators.

    I'm a big fan of their technology and have been looking forward to something with the advantage of an AIO and longevity of an air cooler. Given the cost of the good AIOs for TR/Xeon W already crosses $300 the price for the TR version doesn't seem too awful. The pricing for the client one just seems a bit too high. It costs $100 more than the forthcoming Hyte Q80 (which is already very expensive) and I'd be surprised if it cooled better. I hope it's good, but when you can get top performing regular 360mm AIOs for $120-200 the price tag just seems questionable.

    No pump, so mechanical failure is dealt with.
    Copper evaporator and aluminum condenser... If it's going to cost that much, they should've just gone copper on the whole thing.
    There's a serious lack of full copper options as it is. If folks are willing to spend 200+ on Corsair and NZXT's overpriced stuff, there's no reason not to have more all copper units available.

    Like the idea but does it have brackets to hold it or does it mount to the top of you case not sure i would want that weight hanging off my socket !!

    The actual site shows better pictures that there are rubber hoses allowing for top mounting !!

    so why no pump ?

    Sounds good, except for the price. When the capable, yet terribly named Corsair iCUE Link Titan RX 360 RGB is $200 and carries a 6 year warranty, you could write off two over 12 years and still be cheaper.
