KELVIN

Precision thermal hardware — Helsinki, since 2019

KELVIN°

Gaming hardware has one opponent, and it isn't the other team. We build the coolers, fans, cases and power that keep a machine composed at full load — machined, binned and tested like it matters.

    Microfin array

    0.1 mm skived copper — 94 channels, one billet.

  5. 05

    Cold plate

    C1100 copper, lapped flat to 5 µm.

Every LOOP K273 ships with its own 48-hour test log. This is the part of the product you never see — so we drew it.

Cooling is a trade you make with your ears. The K273's curve is engineered so the trade stays honest — find the point you can live with and it will hold it, all session.

04 / Lineup — six parts, one temperature

05 / Discipline — what premium actually costs

0.1 mm fin pitch

01Skive, don't solder

Cold-plate microfins are cut from the copper billet itself — 0.1 mm fins, 94 channels, zero thermal joints. A soldered fin is a future failure; a skived one is the same piece of metal.

5 µm flatness

02Lap to five microns

Every cold plate is lapped flat to within 5 µm across its face. Paste fills imperfection; we prefer to remove the imperfection.

± 2 % matching

03Bin every fan

Fans are speed-tested after assembly and matched within 2 % per pack. Matched fans stay in phase — mismatched ones beat against each other, and you can hear it at night.

48 h at load

04Test for 48 hours

Each sealed loop runs two full days at load before it gets a serial number and a box. The test log ships with the unit. If a unit is going to fail, it fails here — not on your desk.

06 / Fit check — will it fit? Answered now, not after unboxing

A — Your CPU socket
B — Your case

Anything that clears both checks ships with the right mounting kit in the box — no brackets sold separately, ever.

Two answers.
Zero returns.

Select your socket and case on the left — we'll tell you exactly what fits, with the millimetres to prove it.

6-year warranty

10 on the CURRENT 850. Registered automatically with your order number.

30-day returns

Ran it, changed your mind, send it back. We re-test and re-sell it as open-box, honestly labelled.
