Alphacool Eiswolf 120 GPX-Pro Review
While Corsair and NZXT’s all-in-one (AIO) liquid cooler GPU adapters work quite well, they aren’t particularly easy to install, they’re not as good at cooling as a proper water block and they aren’t particularly attractive either. However, Alphacool’s Eiswolf GPX-Pro aims to combine the best of both worlds. What’s more, it can even water-cool just your graphics card out of the box, without needing to be attached to an existing cooling setup.
It uses a standard 120mm-fan radiator, with two 120mm 1,700rpm PWM fans included. This radiator is attached to a full-cover GPU water block, which has an integrated pump. The radiator acts as a reservoir, so there’s no need for a separate one, or indeed a separate pump. What’s more, the pump is extremely quiet – only the likes of NZXT’s new Kraken series AIO liquid coolers compete regarding noise on their lowest pump speed setting. The fans can be tuned down to inaudible levels using your motherboard too.
Meanwhile, the tubing sports two quick-release fittings, so it’s easy to connect a CPU water block or additional radiator later. The water block itself comes in a few flavors to cater for various PCB designs of GeForce GTX 1080 and 1070 cards, although they’re not all supported. We used a Founder’s Edition GTX 1070 card, which requires the M01 Eiswolf. You’ll need to remove your card’s cooler, and installation is a tad fiddly due to all the thermal pads you need to apply, plus a backplate is included too. A 3-pin fan header powers the pump, and there’s a 4-pin splitter cable for the two fans, plus case mounting screws.
We pitched the Eiswolf 120 GPX-Pro against our card’s stock cooler, as well as a custom loop with a Laing DDC pump and EKWB GTX 1070 water block, but using the same radiator. With the stock cooler, the peak delta T was 60°C (equating to 81°C in GPU-Z), but the Eiswolf 120 GPX-Pro-cut that temperature to just 40°C, while the EKWB unit cuts it further to 38°C. The extra cooling also enabled the GPU frequency to boost further, with the Unigine Valley score rising from a stock-cooled 3,882 to a water-cooled score of 3,955 for both water blocks.
