Raijintek Aidos CPU Cooler Review

Admin Cooling 1327


We recently reviewed the Raijintek Themis CPU Cooler from Raijintek and we liked it. Raijintek have around nine CPU air cooler offerings one of which we have for review today, the Aidos CPU cooler.

Another CPU Direct Contact design; this is a slightly smaller CPU cooler aimed more at the mid-range market or the small form factor segment. Raijintek call this a compact size cooler that is designed to fit most chassis and motherboard combinations. As we said in our Themis review, Raijintek are a relatively new company, established in 2013, and they have an interesting product range.

The styling of Raijintek is similar as you would expect across the range. There is not much excess, it’s functional and to the point.



All fittings above and some spares. You can also fit a second fan if required, nice at this price range.

Raijintek Aidos CPU Cooler Review

Package - 8.4
Performance - 8.9
Price - 10
Consumer Experience - 9


It is a good little performer, and because its a tall cooler with eight heat pipes, you do have a little more confidence it's not cooking your i5 CPU during heavy sessions. Our overclock test was approximately a 20% overclock, not the greatest, but will give you some headway in gaming and applications, without throttling the CPU due to heat, not bad for £14.99.
