Hello... Starting with a clear yes, installing a power supply is quite risky, yes I'm very cautious, and I've already done it before. Now regarding the issue... My PSU has a noisy fan, which seems typical for EVGA models. Since I purchased it used, it isn't covered by warranty even if it were new. I tried reaching out to the manufacturer, but they didn’t respond. So I’m left with replacing the fan. I’ve learned that matching specifications are crucial because the PSU controls fan speed via voltage. Using a unit with different RPM or power requirements could cause overheating and further complications. Since I’m not an expert on energy systems, I’m uncertain about potential risks. Should I worry about higher RPM capabilities or current draw? From my research, the fan in this PSU is a Globe RL4Z T1352512HH—140mm, 12V, 0.45A, 1200rpm, 129.76 CFM. It’s available only on AliExpress, and swapping it might lead to the same problem I’m trying to avoid. One alternative I found is a Noctua NF-P14s, but it runs at just 0.1A, which seems inconsistent with the original model. My main question is: should I go with the Noctua or seek another solution? If I need a replacement with a faster RPM option, what voltage range should I target? Would a fan with higher speeds be acceptable? Do you have any suggestions for something that ships quickly? Because I don’t have a spare PSU and a new one would be too expensive, I really need something fast so I can avoid being stuck without my PC while the noise becomes intolerable.
You can proceed if you possess the required abilities and understanding. From a reliability and safety perspective, it would be wise to save $50-$100 and purchase a power supply that is known for its dependability, allowing continued use across your next three PCs or more.
apply a lubricant to the fan and see if it improves performance. If not, consider a 140mm model such as the Arctic P14 or similar. You may need to modify the PSU header, which will require some soldering.
I really hope I can manage to buy three PCs when I can barely afford a power supply. It would be great if I could just pick a quiet fan instead, since the PSU is working perfectly fine.
I'm still unsure about whether higher RPM parts are safe or if lower amp usage is acceptable. I chose the Noctua model because it matches the same RPM and voltage, drawing only 0.1A instead of 0.45A, hoping it will work fine. I want some confirmation or advice to make sure I'm making the right choice.
I don’t think you wasted a huge sum (over $10)? Otherwise you’d have been better off selling the PSU and getting a higher-quality unit such as the RM850x or similar. What matters most is the airflow, and the amperage needed by the fan comes from the motor itself. If you aim for 0.45A, you’d likely need to boost it above 24V, but the PSU only provides 12V, so you might have to modify the connector. It looks like the original fan uses a two-pin connector.
Lol 10$ sounds about right for an open box deal. For the amps, it was closer to 60$ when unused. I thought that would apply to them too. I wasn’t too concerned about power draw as long as everything runs smoothly and the PSU manages speed. I was thinking about a higher RPM model, but wasn’t sure if that’d cause any problems. It seems cheaper to get one with the same RPM. Since I already need a 3-pin to 2-pin adapter, it should work fine. Now I just need to think about securing the wires without them slipping in the PSU—maybe electrical tape will help.
We were discussing replacing the fan, likely you should have considered purchasing a used RM850X or similar since they typically cost around $50 and offer better options.
Hey! The fan cost only 16$, which wasn’t too much. Since it’s a noctua model, I’m sure it won’t move around much. The adapter cord was 5$. It’s nice I got the replacement part too—the original fan stopped working and was getting sluggish. Once I installed it, it ran smoothly without any grease or issues. I managed to remove the connector carefully, even though I nearly pulled it off the board. Switching fans felt smoother than expected; I almost snapped the connector from the PSU just to be safe. Changing it went better than I anticipated, though I nearly yanked the connector out while trying. I didn’t buy the rm850x and went with my DIY fix because I relied on the PSU list to pick something reliable. I checked online, but most options were used, had missing cables, and were at least 30$ more than usual. With disability benefits, my budget is tight, so I also upgraded the motherboard, case, fans, RAM, etc., and rebuilt the whole setup from scratch. Replacing the fan was a solid learning moment. Thanks for confirming the amp issue—I felt more confident installing it now.
