I recall when these first appeared on the scene, every spec enquiry was psu=hyper type r, then pop, was the same when tagans first arrived, then they developed the tick tick of ticking tagan. I bought one about 12 months ago, after they apparently fixed them. My kit is never off, it ran no problems and is still running a rig further down the line
ive just brought a hiper 580watt psu (not the type r, just the standard) the case for the psu is made up of vents (only one solid side i beleive) but its been running my pc for a week or so now flawlessly. i dont let dust build up that much i tend to clean my pc out once every couple of months or so (havent got any dust filters) but in my new pc i am thinking about getting dust filters. i origionaly had an xpro 470watt psu that gave up the ghost so i got a cheapo winpower 750watt psu which quit on me after a couple of months so i decided to get my hiper 580 and i have not had a single problem with it. ive calculated my total system load (at every component at 100% aswell as 25% cap aging) and it comes to about 530watts so this hiper should be fine for a year or so provided it doesnt "pop" but when i was reading reviews of this psu i didnt come accross anyone saying about them failing infact i never recall seeing a single bad review about them. and to my understanding the type r's are exactly the same as the standard but without the flashy fan and modular bits (in other words all the internals are exactly the same)
My Hiper started making a loud clicking noise, couldn't be bothered to pay to send it to Hiper and wait weeks while they send out another.
Took the top off, then took the fan out and found that the blades were catching on the sides of the fan casing.
I was going to buy a replacement Hiper fan for £3 but fixed it myself. If the screws that hold the fan in place are too tight, it will start to click. Over time the heat causes the fan blades to warp slightly by a fraction. Tell tale signs are the silver paint coming off the blades.
Take the rear fan out, disconnect the 3 wires then attach to a separate psu that you power home gadgets with then torque the bolts one at a time until the clicking stops.
Or replace with a 80x80x15mm fan.
Apparently quite a common problem with the Hipers. The big fan was covered in dust.
