Gentle Typhoon D1225C12B7AP-29 (with the KÜHLER 620) – there is nothing Gentle about that airflow NOR noise

Ever since I bought the fan controller, I had been considering buying the Gentle Typhoon AP29 fan for the Antec KÜHLER 620 radiator. The fan I was using, the Scythe Kama Flow 2 1900RPM model, was reasonably quieter and slightly underperforming compared to the stock Antec fan. But I wanted to see if I could improve the KÜHLER 620’s performance by adding a high speed fan. Tests performed at SilentPCReview was showing that the KÜHLER 620 was only 1C warmer than the 920 if same fans were used. KÜHLER 920 has two fans and  those fans ran at a very high RPM (hence intolerable noise at full blast). So my idea was to buy fans that were on par or better than the stock 920 fans.

I started with one AP29 fan. The noise rating meant that the AP29 was only 3dB louder than the Kama Flow 2. That means, a single AP29 should be as loud as two Kama Flow 2’s. (+3dB means doubling noise, in case you were wondering)

Silencing the PC (part 2)

First of all, if you haven’t already, read the part 1 here.

So I decided to buy a fan controller, no thanks to the amount of fans I have installed in the PC and no thanks to the crappy fan controller on the ASRock Z68 Extreme4 (non-gen3) motherboard.

Whom did I turn to? Scythe. They have the cheapest accessories in Japan, because Scythe is a Japanese brand. But which model? I had a tight budget, so I could not go with fancy touch screen control stuff. (I don’t think Scythe made such models, but if they did, it would be outta my budget.)

I went with the Scythe Kaze Master Ace. I bought it off Amazon for JPY3,437 which was reasonable for a 6-channel fan controller. Sure, it doesn’t have PWM support, but I don’t have any PWN fans anyways so no big deal.
