Advantages of the CapSwap VRM Fan Module

Our iCUE LINK CapSwap VRM Fan Module is an awesome accessory to compliment our iCUE LINK and iCUE LINK TITAN AIOs. However, aside from its cool aesthetic - what exactly does it do? We cover its functionality and advantages below.

First and foremost, we have to address the name of this module - "VRM Fan Module". The VRM is your motherboard's Voltage Regulator Module, a circuit that converts and regulates the voltage supplied to your PC's CPU, GPU, and memory. They especially play an essential when it comes to overclocking. As a result of its job, the amount of heat generation can be immense. With an overheating VRM, you're bound to encounter issues such as CPU throttling, instability, decreased component lifespan, and more.

The VRM is located to the left and above the CPU socket on your motherboard. On motherboards that are more oriented towards performance, they will have heatsinks on top of their VRM for adequate cooling. However, if your PC does not have adequate airflow, then the VRM heatsinks may not suffice. Proper cooling for the VRM is especially emphasized if you are overclocking your CPU.

As we see in the image above, the VRM Fan Module pushes air through its channels on every side. This effectively cools surrounding components, which leads us to our next advantages.

We designed the VRM Fan Module to be dynamic and cool multiple components simultaneously. Aside from the VRM, this module has proven to be favorable for DRAM and the M.2 located just below the CPU. PCIe 5.0 M.2 SSDs especially can run hot due to their ultra high-speed data transfer speeds - hence why you may see some with an active cooler on them rather than just relying on a passive heatsink.

With the VRM Fan Module, airflow is directed at the M.2 slot just below the CPU - preventing throttled transfer speeds and ensuring a prolonged lifespan of your PCIe 5.0 NVMe SSD.

While we've just quickly informed you of the benefits - we also have the numbers to back it up. We utilized Cinebench 2024 & CrystalDiskMark as our stress tests to push components to their limits and to see just how effective our VRM Fan Module is.

Test bench specs:

• CORSAIR iCUE LINK TITAN 360 RX RGB
• Intel Core i9-14900KF
• MSI MPG Z790 EDGE TI MAX WIFI
• Power limit set to 288W

The numbers speak for themselves.

• VRM - as much as 29% difference (mind you, the tested motherboard has quite a beefy heatsink. Motherboards with a less capable heatsink would yield an even higher difference)
• M.2 - as much as a 44% difference, and it actually hit a throttling point at 80C without a heatsink/cooler
• DRAM - as much as a 30% difference
