Alphacool EISBAER Ex BLACK LCS review -
Core i7 8700K OC at 4800 MHz 1.3 volts
Core i7 8700K OC at 4800 MHz 1.3 volts
1.3 V and higher voltages can cause serious problems for Coffee Lake CPUs because of the TIM used under the heat spreader (instead of solder like in the Sandy Bridge range). Our (delidded) Core i7 8700K was set to 4800 MHz, at 1.3 volts. We used wPrime 2.10 (3 times, 1024 M) this time as well. IDLE temperature measurements were taken in the desktop, with almost no stress to the CPU.
The temps shouldn’t go beyond 90°C, as otherwise the CPU might degrade and also throttling can occur (especially applicable to the AMD Ryzen range, which normally operates at lower temperatures). AIO coolers usually perform very well with our delidded Core i7 8700K. The Alphacool EISBAER EXTREME BLACK EDITION is not an exception, we can even say it's excellent (considering the noise output). Let’s try it with a voltage higher than 1.3 V.
Core i7 8700K OC at 4800 MHz beyond the 1.3 volts
There are five stages for the charts below:
- Default
- 4.8 GHz @ 1.3 V
- 4.8 GHz @ 1.35 V
- 4.8 GHz @ 1.4 V
- 4.8 GHz @ 1.45 V
The Alphacool EISBAER EXTREME BLACK EDITION managed to keep the CPU temperatures under control until 1.45 V. The final result is great, the best we’ve seen so far.
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.
