This setup allows you to install three 120mm fans at the base (unless your ATX motherboard is too long) and two for side intake. Upgrading to higher CFM case fans could also be a smart move. I’m considering the 95 CFM Cooler Master JetFlo, which would be an upgrade from my previous 69 CFM non-PWM SickleFlow X model. It seems more economical to purchase the A35 unit plus three JetFlos than to buy a 240mm AIO for 139 AUD. There’s also a chance I might skip buying new fans if thermal testing reveals they’re not needed.
Good observation, but I'm curious if these maximum power ratings can actually be applied for comparison across the Ryzen series—like the 3900X, 5950X and 5800X3D all have a 105W rating and fall within the same range, so a cooler that works for the first two should likely suffice for the third as well.
I shared multiple assessments indicating that the peak power draw for the 5600x model hovered near 90 watts. I also own a 5800x as displayed in my profile. Your experience stands out since you managed to achieve around 130 watts by turning off hyperthreading and adjusting BIOS settings to essentially push your CPU to its limits. Not everyone will attempt this, and it's not a universal approach. Yes, the 5800x3D includes an additional 64 MB of cache, but it also has better binning and limited overclocking options, which means the extra RAM power usage isn't substantial. Here are some reviews: power readings at the CPU cable range from 115-118 watts for the 5800x3D compared to 139 watts for the 5800x; handbrake's software encoding test shows 108 watts for the 5800x3D versus 142 watts for the 5800x. GamersNexus reported 108 watts at 12V power connector, while the 5800x uses 127 watts (see 8:30). Overall system stats: 5800x vs 5800x3D – idle rates around 69-76%, single-thread performance near 107-109%, multithread around 219-219 watts. TechPowerUp noted 168 watts for the 5800x3D under load versus 176 watts during stress testing. Remember, these figures are measured at the wall outlet; higher wall consumption usually reflects greater losses. For instance, Guru3D's tests used a 1200W PSU with 92% efficiency at low loads (around 200-300 watts), resulting in actual component usage around 70 watts at idle—about 76% of that being consumed by the CPU itself. You'd still need to factor in RAM power, which tends to be lower during idle.
I'm not alone in this. I didn't turn off ht, just turned on PBO, +200, boosted my power limits, and adjusted the curve. If I used a static 4700, it could reach 155w PPT. I don’t own a 5800X, but I have a 5900X, and with PBO etc., I can get 235w PPT from it. Since I began sharing my power limits, many people keep repeating them. Just some food for thought.
Exactly... the documentation on the box or in the manual usually includes this information. If you install the CPU into an A520 chipset motherboard, these settings are typically available by default. You don’t need to refer to personal tweaks—standard behavior is to plug it in and add a cooler if needed. The power usage shown is the baseline, not something you adjust based on individual experience. You can still experiment with BIOS or tools to increase consumption for performance gains, but that’s optional.
I never handle stock figures since I don’t manage any stocks. My role is simply to inform you about the benefits of air cooling. The improvements are real and happen significantly quicker than with traditional methods. That’s why individuals like me choose this approach.
Yes, work is possible but likely close to the limit. My 3D already handles up to 125W/85°C, and I've been using CB23 for about ten minutes. Adding GPU heat would make it less stable. Maybe my NH-U12s performs better than expected. Unfortunately, I can't find a trustworthy wattage rating for the Noctua coolers.
