The idea for cooling the Asus Prime B450M-A MOSFET comes up in a solution discussion.
Hi, id like to push my r5-1600 to higher clocks but im concerned about my mosfet temps so i figured out i could do some DIY heatsinks.
I found some online shops selling aluminium heatsinks and thermalconductive double sided tapes and im torn between how i should go about it...
Option A: buy multiple small heatsinks and have each one for couple of mosfets - i would need 6 separate heatsinks to cover all of them
Option B: buy two long heatsinks and have it cool all the mosfets in a line.
My cpu cooler will be amd wraith prism so there will be quite abit air going down on the motherboard already but im wondering if it will be enough for such purpose.
Buying higher tier motherboard is not really an option because im trying to spend as little as possible. I know i should have bought mobo with them when i was building pc but hadn't had idea that overclocking will be so fun to me as it's first time im trying some serious oc.
My cpu is stable at 4.1 ghz but quite hot, i have a feeling that with proper cooling and mosfets with heatsinks on i will be able to push it to 4.2 or higher.
You may wish to share your current system's specifications in this way:
CPU: Motherboard: RAM: SSD/HDD: GPU: PSU: Chassis: OS:
Before starting your overclocking journey, remember that quality and tolerance are essential when applying stress. You also missed including the links to the heatsinks you're considering.
Unfortunately, it's not just about the 6—there are smaller surface-mounted power delivery modules near the chokes as well.
You might want to think about purchasing a new board with a stronger power delivery heatsink, since a failed board will prompt you to buy one again.
CPU model is r5-1600, built on asus prime b450m-a board. RAM capacity is 16gb ddr4 with hyperx 2666mhz OC to 2933. Storage includes a kingston a2000 m.2 ssd of 500gb. The GPU is a gtx 1050ti. Power supply is a thermaltake smart bx1 550w with 80 plus bronze. The chassis used is zalman s2. Operating system runs w10. Previously, I achieved over 4.1 ghz on oc with wraith spire cooler, but temperatures were too high. My airflow setup has a rear fan at 1500rpm and a top fan near the cpu heatsink for exhaust at 1200rpm. Even if I push my CPU to its limit, the GPU remains a concern, but it’s not a major issue for me. I’m mainly interested in testing how high my CPU can go. Currently, my CPU operates around 3.9 ghz during daily OC.
The 4.1 GHz frequency is quite high for a 1600, so what might be limiting you is likely the VRMs. Rear and top should handle exhaust, while front fans are meant for intake.
And you ignore the GPU. The SSD. The SATA controller, Northbridge chipset. All your air flows in, hits the CPU fan directly, then rises. There’s no proper circulation in the lower sections. Any parts there get damaged. This isn’t about proximity to a wall or my setup in a cubby—it’s about how heat moves. In one direction and out the other, it gathers warmth from everything. You only capture heat from the socket area, blocking any air movement elsewhere. Your high performance needs are only useful for testing, not for long-term use. A SATA controller can easily exceed 90°C, and you want it to stay in that hot spot without airflow. Don’t waste money on heatsinks for the VRM; invest in quality fans first. You’ll end up needing to replace the motherboard later.
