Arctic Announces the Freezer 33 Series Semi-Passive CPU Coolers
ARCTIC announces its new Freezer 33 Series. The high-performance semi passive CPU coolers Freezer 33 and Freezer 33 CO are the successor models of the Freezer 32 series. They are equipped with PWM controlled 120 mm cooling fans and offset heat pipes to ensure optimal heat dissipation. The low footprint of the Freezer 33 avoids interference with the RAM, even if there are two fans used. Fast and easy to install and extremely reliable, the mounting system is compatible with Intel and the new AMD Ryzen AM4 socket.
Semi passive cooling makes the Freezer 33 Series very efficient and extra quiet. During simple applications, such as creating documents, the CPU is cooled passively. The F12 PWM fan only powers up at a higher load, starting at 40 % PWM. In this way, an optimal cooling capacity at a low noise level is guaranteed. The Freezer 33 CO is specifically designed for continuous operation. The Japanese dual ball bearing, used in the "CO" version, reduces rotational friction considerably, is significantly less sensitive to dust and high temperature and hence up to 5 times more durable than other bearings.

The temperature is @ ~ 60°C in full load in Prime 95 at stock frequences, which I assume to be a good result. But what dissapoints me is the semi-passive mode that doesn't work for me, i.e. fans are always working, even when PC is idle. No need to say, the noise level is above my expectations.
Guys, maybe I'm doing something wrong?
Are the fans exactly the same, and listed as 0Db start?
I've done as it is said in the manual, plugged one fan into another, and the second to 4 pin connector.
The label on the fans says 'Arctic Freezer 33 Plus ', and the booklet from the box confirmed that this cooler features semi-passive mode.
i would like all my fans to switch off whilst browsing and the like.. not because of noise it would just help keep the dust out..
my cpu fan spins at around 300 rpm.. as slow as i can make it go.. my asus motherboard kept thinking it was faulty and sending me into the bios to put it right.. a pain in the arse every time you boot.. the only way to stop it was to disable the cpu fan monitoring.. :)

Although, I guess, it is more the option of the mobo than the fans.
Nonetheless, thanks everyone for advices, and sorry for turning original post discussion into help section.
