Alphacool Announces Eisbaer LT 92 SFF AIO CPU Cooler

The Eisbaer LT 92 is the little sister of the classic Eisbaer LT. It is without quick release fasteners and is delivered with only 25 cm long hoses. This ensures it fits perfectly into SFF cases. SFF stands for "Small Form Factor" and describes extremely compact housings. Despite its small dimensions, the 92 mm copper radiator offers enough cooling power for powerful processors. Alphacool uses hoses and fittings from the Enterprise Solution series for the Eisbaer LT 92. The TPV hoses are particularly robust and do not kink as easily as the usual PVC hoses. Bend protection is therefore not necessary. The Eisbaer LT 92 is compatible to all mainstream sockets, the appropriate mounting material for various Intel and AMD sockets is included, also a set of fan screws for 25 mm fans. Fans are not included with this unit and must be purchased separately. The Eisbaer LT 92 costs €73.09 (inc. VAT) from the Alphacool web shop.

Nice looking cooler, but was this statement really necessary ??? I mean duh......as in only the newest of newbies would possibly not know what "SFF" stands for, yes :)

Unfortunately for us tech nerds, there are far too many people who want to build their own computer but don't have a clue what they are doing. Sadly that means the statement was probably necessary.

Cute, but ultimately pointless. I like Alphacool's AIOs and would choose them again over the cookie-cutter Asetek/CoolIT stuff that is rebranded over and over again on the market.

I'm guessing this was made as a niche solution for a specific SI or OEM and Alphacool just decided to throw a few more into the run and offer them to the retail channel.

The problem with 92mm radiators is that they simply don't have enough surface area to be a significant improvement over even a small heatpipe solution. In a regular case - even an SFF case, there needs to be airflow around the socket anyway to keep the motherboard VRMs, RAM, and chipset. There's a good market for dual-heatpipe 92mm or 100mm top-flow coolers specifically for SFF builds that provide as much, if not more surface area than what looks to be a 92x20mm radiator.

The extremely short 25cm hoses also make it impractical as the one scenario where this may have been useful would be if the CPU socket was tightly enclosed and difficult to access via direct air path. 25cm barely gets you from the socket to the case edge, once you account for tube bends without kinking.

I'd be curious to see the original case/OEM design this was primarily made for. I can't imagine it's going to be much use for the DIY channel but I'm sure there will be a tiny numbers of sales to that niche within the niche of 'watercooled SFF' that require a short-tube 92mm solution.

As long as people abbreviate wrongly to GB instead of GiB, call 1440p (or was it 1080p?) '2K' for whatever reason and consistently buy into the worst possible product lines, yes. Explain everything.

You are right when you say it is a niche product. We only made this AIO because we have received many requests from the SFF sector looking for such an AIO. There are some very popular SFF cases that enjoy a wide popularity. There is quite often a water cooling system used. Currently many use our Enterprise Solution products for their SFF projects, because we offer extremely small AGBs with pump tops. The high demand from end customers has even led to the fact that we almost had problems to supply our Enterprise customers promptly, because we did not expect this. XD That was a big suprise for us.

Hey that's good to know. Are you likely to offer this in a variant with longer hoses at any point in the future? There are a couple of SFF builds I've done where a 92mm radiator would have been useful, but 25cm hosing would rule this out as a candidate.

I am not sure if we will make a version with longer tubes. Dont think so. I mean, if you need a special version, you can use the Eisbaer LT Solo (only pump/cooler without anythingelse) some tubes you like and a radiator you like. So you can built an own AIO like you want. If the sales will be very high, sure we will make other version. Everything depends on the sales and the requests we get. I mean... never say never ;-)

This doesn't seem to be expendable like most Eisbaer products? :)

That's fair enough, I don't build custom loops because I want the AIO's warranty to be intact for the end user, but it's definitely a valid option thanks.

No it isn`t. The QDCs are mostly to big for SFF cases. Not easy to handle them in such a small case so we canceled them. A fan is also not included, because for some cases a 25mm fan fits, in other cases only a 15mm fan. So you can choose what you want without paying for a fan wich you maybe can`t use in your SFF case.

@Chrispy_
If you buy the parts seprately, the warrenty is like with all DIY parts. So, yes, i think its fair for everybody. :)

This is perfect... I love alphacool stuff for SFF and custom small builds... Currently running the eisbear for a watercooling setup in a jonsbo U4:




I would definitely get this to put in my next build with the k77:


It would fit really nicely as an intake top intake rad offset from the board.

A lot of Dan A4 owners would disagree with you. In sandwich layout cases with low CPU cooler clearance, a 92mm AIO is an excellent upgrade. Many cases have 47-50mm of clearance, meaning the best cooler options are typically the Noctua L9 series or the Alpenföhn Black Ridge, both of which are noticeably outperformed by a 92mm water cooling setup. The Asetek one that has been around a while is quite good, but this should be noticeably better with its copper radiator. Paired with the excellent Noctua NF-A9x14 this is a really potent CPU cooler in a very tiny package.

Didn't you already post that, just above my post?

Yeah, I'm using an L9i in one of my machines. It's tiny; Too tiny - definitely less surface area than a 92mm radiator.

Yep, but surface area can't be compared 1:1 between water and air coolers either - the fins in a radiator are on average much closer to the thermal transfer medium than the fins on an air cooler, making them more efficient per unit of area. The higher temperatures of air coolers and heat pipes counteracts this some, but not completely. Radiators make better use of what surface area they have available.

Make a version with QDC hoses (couplings both ends) and make the hose length an option at the time of purchase, that way the initial buyer is happy and subsequent buyers of a used product has the ability to purchase a hose separately to suit their build.

I thought that since the pump is the Solo LT it might have been possible to disconnect two of the fittings, and use the pump and radiator in a custom loop with a 240mm rad for the GPU. Is this not possible?? Bc otherwise I would need to buy the LT Solo which is 60€ + the ST25 which is another 40€. So around 30€ more and with no fittings and tubes. (I know water cooling is expensive and another 50€ isn't that much in context, it's just that I have a 200€ budget and this problem kinda wrecks it :( )
If u could clear this up it would be awesome, anyway really like the product even if this is not possible. The sff space needs more products and it's awesome that u guys released this for 30€ less than Asetek 645LT.

I can see this being useful in ITX cases, especially half height ones

Niche for sure, but theres a market for this

Is there a difference here between the Eisbaer LT Solo and the pump/block that comes with this? I noticed apart from the nickel plating , the Eisbaer LT 92 is rated at 70L/hr vs. the LT Solo at 100L/hr, though it appears to be the same pump and housing?
