<h2>{{ .Title }}</h2>
<p>While getting my X58 SLI build together (more on that soon), I needed to diagnose a beeping from my power supply. It's an old model Enermax 1000W, but packs some usefull features including overcurrent protection and fan abnormality notifications by means of a speaker inside the PSU. I could tell something wasn't quite right on the first boot. There would be an occasional scraping sound and the PSU would frantically beep loudly in short succession. I quickly deduced it was the fan.</p>

<p>As it's an older model, finding support can be difficult. Luckily I found a <a href="https://pcper.com/2006/10/enermax-galaxy-1000w-1-kw-power-supply-review/2/">PC Persective review of my exact model</a> which included a teardown and look at the fans.</p>

<p>Sourcing an exact replacement was looking to be a difficult task, and I'd read other reports of people replacing power supply fans only to have the supply trip its protection measures due to the new fan not performing identically to the original. Seeing as this particular model may be even more tempremental than a more modern unit, I wanted as exact a replacement as I could get. Unfortunately, finding a fan that had the same connector was proving to be futile. I decided to open it up to see if I could tell what kind of damage there was.</p>
<p>I expected some kind of bearing failure due to dust, and upon disassembly, I noticed that the blade assembly had a lot of vertical play. Figuring I couldn't do any more damage, I pulled the assembly straight off the hub. To my suprise, a standard roller bearing and spring popped out... further down the hub, I could see a second. Peeling off the rear sticker revealed the real issue. The circlip attached to the fan blade shaft was too weak to hold the force of the spring. I was lucky and had some flat washers on hand that were nearly the perfect size. After cutting one side to resemble a lock washer, it installed perfectly onto the shaft with great retention force. I reassembled everything and it spun perfectly.</p>
<p>I was beyond impressed. I'm sure the motor efficiency is poor, the fan is hard to come by, and the fact that the clip failed was disapointing, but the fact that I was able to cobble it back together with a washer and some inginuity makes up for it in my book. No need to replace what you can fix.</p>
<p>Just another reason old is good.</p>
