Raspberry Pi 4 Model B Dual Fan With Heat Sink Ultimate Double Cooling Fans Cooler Optional For Raspberry Pi 4B/3B+

Everything works. In passive mode, the temperature immediately fell from 45 * to 40 *. With a blow fell to 36 *, under load does not rise above 38-40 *. At room temperature + 25 *. Load as a web server. With a regular radiator, the temperature under load was 53-56 degrees. The coolers can be heard at night. If two meters from them is. To Novosibirsk drove about 95 days.

Lowers the temperature by 10-15 degrees, at 4ka had to remove the radiator from the adjacent chip, which is lower in height, it is now not cooled.

Everything as described. The fan works pretty silent for me. A little bit slow delivery to Bulgaria not depending on the seller. I recommend.

Good item. As described. Two 5V fans are installed on top of aluminium heatsink. Airflow is a bit weak, though.

stribede in fine condition. untested but it's a simple dual fan with 5v power. should work without a hitch.

Delivery 2 weeks to Eastern Europe, all as described, I recommend to all this store and its goods

very nice piece of fan however quite noisy - I shall use PWM to make it working only when needed

All right, good packaging, the product is of great quality, all working I recommend

Is not for RPI 4, because the heat sink is not touching the RAM, only processor...

Haven't tried it yet, but looks great, arrived fast. No complaints!

I havnt still use but its look good. Fast shipping. Recommended.
