Purpose & Audience

The Aa Pub THETA 31 is a 100 mm tower air cooler built for Intel sockets LGA 1156, LGA 1155 and LGA 1150. It targets owners of legacy Pentium G, Core i3, i5 or i7 systems who need a quiet replacement for a stock cooler.

Who It Suits & Who It Doesn't

Builders restoring or upgrading older LGA 115x platforms will appreciate the hydro-bearing fan rated at 1800 RPM and the 3-pin power connector. It is not suited for systems requiring higher airflow than 10–15 CFM or for motherboards using different mounting hole patterns.

Deciding Specification

The copper-core heatsink measures 97.5 x 97.5 x 60 mm and weighs 450 g, so the cooler fits only cases with at least 60 mm of CPU clearance and motherboards that keep the socket keep-out zone free.

Questions about this item

How long will the Hydro Wave bearing last before the fan needs replacing?

The Hydro Wave bearing is rated for continuous operation at 1800 RPM with a rated current of 0.08 A, and the cooler weighs 450 g, indicating a robust build for long-term use.

What thermal limit does the copper-core heatsink hit first during prolonged loads?

The cooler delivers 28.8 CFM airflow at 25.2 dB noise, so the practical limit is the 100 mm fan's maximum 1800 RPM speed under sustained heat.

How much noise and power does the 100 mm fan produce when running all day?

The fan runs at 1800 RPM, draws 0.96 W max at 12 V, and produces 25.2 dB noise while moving 28.8 CFM of air.
