From the Pure Loop 3 280 to the H115i RGB: five liquid coolers ranked on fan size and cabling, with who should skip each one.
By The PC Journal editorial team
12 min read5 products evaluated
Close to $120 the picks include larger radiators with extra fans and software control. Every pick cost 80 to 120 when we checked and is a sealed liquid cooler with a stated radiator size.
This is a research roundup, not a lab test: fan size, cabling and sockets named come from each maker's published specs; nothing here was tested in-house, and a missing cabling is flagged, not filled in.

Our Picks
Premium Pick1 of 5
CORSAIR iCUE LINK H115i RGB on Amazon (opens in a new tab)
The H115i RGB runs pump and fans through Corsair's iCUE LINK hub, with fans up to 2000 RPM and zero RPM mode.
Best for
- Spending more than the Prime LC 360 White costs for the fullest feature set in this group.
Skip if
- Look at the others if this bothers you: lighting and display control need iCUE.
Why we like it
It belongs in Corsair-based builds. Check that your case offers 280mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks. The maker doesn't spell out LGA1851 mounting, so confirm it on the maker's site for a Core Ultra build.
Plan to install iCUE for lighting control; fan and pump speed can also run from the motherboard's headers. Another plus: 20-LED pump cap. Before buying, weigh one limit: costs more than the Pure Loop 3 280 at the time of writing. At our last price check it topped the group, with the Prime LC 360 White the nearest cheaper option.
Key dimensions & specs
- Max fan speed: 2000 RPM
- Fan size: 140mm
- Zero RPM mode: Yes
- Cabling: One-cable iCUE LINK hub for pump and fans

Also Consider2 of 5
CORSAIR Nautilus 360 RS ARGB on Amazon (opens in a new tab)
The Nautilus 360 RS keeps things simple: its fans daisy-chain and connect straight to the motherboard, with no hub or software needed.
Best for
- Buyers who want pump rated at 20 dBA.
Skip if
- Skip it if price comes first: the Pure Loop 3 280 cost less when we checked.
Why we like it
Corsair rates the pump at 20 dBA. Its convex cold plate comes with pre-applied paste in an optimised pattern, and the RS120 ARGB fans use magnetic dome bearings for low noise.
