Asus cards such as the Prime GeForce RTX 5070 allow easy removal of the shroud with the fans, without removing the heatsink itself. This opens room for experimentation with cooling.We will find out how much you can gain by replacing stock fans with a pair of 120mm Arctic P12 Pro A-RGB fans. We will measure operating characteristics from 20 to 100% fan speed and see how much the card\u2019s noise level drops at identical temperatures.<\/p>\n

I discussed the operating characteristics of the Prime GeForce RTX 5070 in a review a few months ago. The sample I tested had one fan noisier than the others. Because of that, the card was not completely quiet even at minimum speeds. The card was more audible than it could have been. However, this would probably not be accepted as a reason for an RMA. With most Asus cards, though, you can easily replace the fans, because they allow the shroud to be removed without taking off the heatsink.<\/p>\n

<\/a><\/p>\n

The Prime RTX 5070 is 30 cm long, but relatively narrow. That means that for active cooling of the heatsink, a trio of fans with an impeller diameter of 9\u201310 cm is best suited. But you can also use a pair of larger fans.<\/p>\n

<\/a><\/p>\n

The heatsink under the shroud is divided into two fin stacks. Thanks to this, two 120mm fans can be mounted so that they blow over most of the fin area.<\/p>\n

<\/a><\/p>\n

In recent tests, we tried sets of three smaller 92mm fans. First, we replaced the trio of Asus Axial-Fan units with three low-profile 92mm Noctua NF-A9x14 fans and Noctua NF-A9 fans with the standard 25mm thickness, and then tested the card with a trio of Arctic P9 PWM PST<\/strong> fans using fluid dynamic bearings.<\/p>\n

<\/a>\"\"<\/a><\/p>\n

Today we return to testing the card with a pair of 120mm fans. In one of the previous articles, we already tried a pair of Noctua NF-A12x25 and NF-A12x25 G2 fans. Two 120mm fans are, however, wider than the original trio of fans on the Prime RTX 5070, so they protrude to the sides and part of the airflow bypasses the heatsink.<\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

Today we will mount two more affordable 120mm Arctic P12 Pro A-RGB fans onto the cooler. The black version already went through the standard fan testing methodology<\/a> on HWCooling in July. In addition to it, Arctic also offers a white version, on which we will test how it handles cooling the Asus Prime RTX 5070.<\/p>\n

\"\"<\/a><\/p>\n

Arctic offers the P12 Pro A-RGB fans both individually and in an economical three-pack. We bought them directly from Arctic\u2019s store, where the three-pack paradoxically costs less than two individual units.<\/p>\n

\"\"<\/a><\/p>\n

The fans come in a simple box. Inside, besides the fans themselves, there are only three small bags containing four screws each for mounting.<\/p>\n

\"\"<\/a><\/p>\n

Some Arctic models carry the PWM PST suffix. This stands for PWM Sharing Technology. If a fan has PST in its designation, it means it includes an additional splitter on the fan connector. Thanks to this, multiple fans can be daisy-chained together to share the same PWM control signal. The cabling is also more flexible and easier to hide under a shroud compared to the Noctua fans connected via the supplied splitters<\/p>\n

Another way to control multiple fans at once is a different type of splitter, which Arctic also offers. Their 4-pin PWM Fan Splitter allows up to four fans to be connected at once. The result is more compact and, compared to chained splitters, also less prone to failure due to poor contact or a connector coming loose somewhere in the chain.<\/p>\n

    First, we will look at how the card performed across the full range of operating speeds with the stock fans, and then go through the operating characteristics of the card with the Arctic P12 Pro A-RGB fans.<\/p>\n
