Rank #6 in Best AIO CPU Cooler 2026: 10 Ranked, and the Spec Numbers That Disagree
NZXT Kraken Core 360 RGB
Price and rating as shown on Amazon when we collected them. Both change.
The NZXT Kraken Core 360 RGB sits at number six in this guide to 360mm AIO CPU coolers, and at £69.98 it is the cheapest of them. It carries a 4.7 rating from 198 reviews, and the spread is tidy: 84 five-star ratings against six at three stars or below. It is also, on this page, the cooler whose own numbers cause the least trouble.
The finding here is less a contradiction than a missing label. The first bullet calls it a "3,100 RPM pump", and the spec table prints the same 3,100 RPM under "Max Rotational Speed" — a heading that on most AIO listings describes the fans, not the pump. Nothing on the page says which of the two it means, so that figure still cannot be lined up against a cooler that lists pump speed and fan speed as separate fields. The airflow number needs the same care: 75.05 CFM, with three fans in the single frame, and no note of whether that is one fan or all three. What holds up is the wattage, 12.12 watts, which falls inside the 1.8 W to 16 W band the other 360mm AIOs here use — so unlike the PF360's "320 watts", this reads as a power draw and not a TDP pasted into the wrong field. The noise figure is where NZXT parts company with the Corsair and MSI listings in this guide: the bullets say the pump minimises noise, and the spec field puts a number on it at 31.9 decibels, instead of a whisper in the copy and a louder figure in the table.
Everything on this page comes from the Amazon listing, not from our own testing.

Questions people ask
Is the NZXT Kraken Core 360 RGB the cheapest 360mm AIO in this guide?
At £69.98 it is the lowest price among the 360mm AIOs in this guide, and it carries a 4.7 rating from 198 reviews.
What noise level does the NZXT Kraken Core 360 RGB list?
The spec field says 31.9 decibels, while the bullets promise a pump that minimises noise. The 31.9 dB is the figure you can actually compare with the other coolers here.
Does the 3,100 RPM refer to the pump or the fans?
The listing never says. The first bullet calls it a 3,100 RPM pump, while the spec field is headed Max Rotational Speed, which on most AIO listings describes the fans.
How much power does the NZXT Kraken Core 360 RGB draw?
The wattage field says 12.12 watts, which sits inside the 1.8 W to 16 W range the other 360mm AIOs in this guide use, so it reads as a power figure rather than a cooling rating.
What is the airflow figure for the NZXT Kraken Core 360 RGB?
75.05 cubic feet per minute. The single-frame design holds three fans, but the listing does not state whether that airflow figure is for one fan or all three.
Does the NZXT Kraken Core 360 RGB need a separate controller or software?
The bullets say it connects directly to your motherboard with no extra controllers required, although the item highlight describes it as CAM-ready. The listing gives a 5 year manufacturer warranty.
