Alphacool NexXxoS XP Core i7 water block review -
Testing and benchmarking @ 3200 MHz
Testing and benchmarking
Now that the system is hooked up and actually working with a cooling solution, let's run some performance tests. Initial thoughts: very exciting. We set our room temperature towards roughly 21 Degrees C for an objective comparison.
Mind you that we cool, nearly passive, the Zalman Reserator XT is used here.
The setup used for Project X:
- Smooth Creations paint job+chassis
- Core i7 965
- ASUS Rampage II eXTREME x58
- 1200 Watt PSU
- Corsair Dominator DDR3 1866 MHz
- GeForce GTX 295
- Alphacool waterblock
- OCZ SSD
- WD Raptor 150 GB
And excluding small stuff like DVD-RW etc, this project is very expensive and runs over 3500 EUR.
Right after system boot up the water obviously is cool at room-temperature, the components will be slightly warmer over a longer timeframe due to the nature of water-cooling.
Core i7 965 processor @ 3200 MHz (default)
For our first test we are going to look at the cooling performance of the kit. First let's focus at non-overclocked results. Out mainboard has extra power phases and typically wattage and temperatures run a little higher than your average system.
We tested the processor both in idle (nothing to do) and 100% stressed on all four cores with Prime95 software.
- Processor clocks at 3200 MHz (~3340 in Turbo mode).
- Zalman Resorator set at LOW - our primary mission here is to achieve a noiseless environment
In an idle status we see the processor roughly hover at 31 Degrees C / 88 F. Once we stress the four CPU cores real hard, almost unnatural for the PC to do and achieve, we peak at roughly 49 Degrees C / 120 F.
The is just perfect for a high-end processor when not overclocked, with no noise at all.

Today, we are reviewing an AIO cooler from Alphacool; it’s an Eisbaer Aurora 360 HPE. We already had a chance to check its predecessor, the Eisbaer Aurora 360, back in 2020 (and it earned the “Recommended” award) and the Extreme Black edition of Eisbaer at the end of 2019 (and it was awarded the “Top Pick” badge). How will the new one perform?

Alphacool HF 38 Niagara Intel Core i7 CPU water block review
There aren't that many companies out there that offer liquid cooling products which you can purchase separately. There's a handful of them. One of them is the German based Alphacool. Recently they introduced a new CPU block called the Alphacool HF 38 Niagara. This new water-block is designed for Socket 1366 processor, aka Nehalem aka Core i7. A high-end liquid cooling CPU block priced fairly. Let's check it out.
