For the last couple of weeks or so I've had an annoying little "tick" coming from my PC case. The components are just about 3 years old. Built in Jan 2020, and have only changed the GPU, SSD, and CPU cooler since then). The specs are: Asus X570 Crosshair VIII Hero AMD Ryzen 5 2600x CPU Noctua NH-U12A chromax.black air cooler Soundblaster Z PCIe Asus TUF RTX 3070 2 x 8GB Corsair Vengeance DDR4 2400 2 x 2TB Crucial MX500 SSD 1 x 1TB Samsung 860EVO SSD 1 x 500GB Crucial P1 NVME 1 x 480GB WD Green M2 SSD 1 x Optiarc DVD-RW 1 X Pioneer BD-RW 1 x EVGA 750w BQ Semi-Modular PSU All contained in Corsair 750D Airflow Edition full tower case with 4 Bequiet 140mm Pure Wings fans. I've gone through the following diagnostics - all fans (except brand new cooler which is a week old), disconnected, and reconnected one by one. Sound is still there. All fans disconnected entirely and just run with CPU cooler, sound is still there. I think I've tracked it down to the PCH fan, which after a few google searches seems to be a common fault with X570 mobos. This morning I even went as far as stripping the system down again, dismantling the fan shroud, taking the fan out (giving it a clean) and even using some silicon grease I use in an Airbrush to "oil" the fan shaft. This seemed to work for a few hours, but sadly the noise has returned... The only item I've not tested/taken apart is the PSU, however, I really do not want to do that as it would mean a lot more hassle. With the steps taken, could there be anything that's like to be at fault? If it is the fan, sadly, according to Asus, and other board manufacturers, the PCH fan is supposedly a "non-user replaceable item".... Any help would be appreciated. Treker_ed (Sorry for the long post, wanted to get as much info to help, and also all steps taken so far to diagnose the problem)
it is replaceable but depending on the fan mounting holes it could be hard to locate the same fan with same moun holes. You could always drill new holes or I myself just mounted a different heatsink fan kit so I can use more generic and normal fan mounts
As you say, it's replaceable, but locating the same fan is almost impossible. I did dozens of searches and the same part number was being used on multiple fans, all similar but the locating holes were in different places! Sadly I don't have the mechanical ability to retrofit any other heatsink or fan to the board - being autistic I can excel in some areas (especially technical areas) but I'm lousy in other areas - especially practical and mechanical areas. Win some, lose some as they say! In the end, after many hours diagnosing, and trying to put up with the sound (again austistic sensory issues come to the fore....) I just had to pull the trigger and get components swapped out. I'e now gone with the following upgrades: Ryzen 5 7600x AM5 Processor Asus B650E-E Gaming Wifi AM5 Motherboard 32GB (2x16GB) DDR5 RAM (and due to less SATA ports - Startech.com PCIe 2 port SATA controller) Kept all the other components, except for 1 x M2 Sata SSD - not compatible with the new board! It's annoying that for the price of the new AM5 motherboards, that we are getting a lot less expansion, for a lot more money. On the old X570 board I've just swapped out, it had 8 SATA III ports, 4 PCI slots, and 2 NVME slots. The new B650 board (and even the new X670 boards are similar) only has 4 SATAIII ports, 3 PCIe slots, but does have 4 NVME slots. Lot less for a lot more money! Now that the system is up and running, I'm happy with it, and is running very sweetly, and smoothly. Just wish I did not have to update so soon in comparison to my previous rig!
i must say the whole x670 or am5 overall is a weird chipset for cost. regardless of the excuses I have seen from the manufacturers. but profit is up (for actual sales not counting non moving inventory) so there is your answer
This whole thing got mot more expensive... Just after I built up the new system, it seemed to be running ok for a couple of days, I started to hear another "tapping" noise coming out of the case. Knew it could not be the GPU, knew it wasn't the CPU cooler, what the hell is it???? After a couple of days diagnostics (un hooking fans etc) tracked it down to the damn PSU! The fan or something in the PSU was off kilter. If the case was laid on it's side, instead of being stood upright, no noise, perfectly fine, if the case was stood up, as it should be, damn annoying, constant rhythmic tapping noise, as if a fan was catching on something, but didn't change speed as the fan speeded up or slowed down based on system load. Anyway, out it came - at this point could not care less if in or out of warranty - PSU came apart! Was filthy inside, so got a good cleaning (I also build aircraft models, so I have an airbrush, and used this to blow out any dust). Now cleaned, including the fan, put back together, and back in the case. Still tapping away!!!!!!!!!! Have now had to replace PSU as well. Extra expense I did not want. Gone with a 850W Thermaltake Toughpower GF1 fully modular PSU. So in the last two weeks, I've replace CPU, RAM, mobo, PSU.. Might as well go the whole hog and replace the case as well... (I am actually thinking about doing that - and been looking at cases - but want one with 5.25 bays as I do actually still use my ODD quite a lot)

(I am actually thinking about doing that - and been looking at cases - but want one with 5.25 bays as I do actually still use my ODD quite a lot)[/QUOTE] Well, I've decided to go for it and buy a case as well... Not the one I had in my sights originally (of course it wasn't - nothing has gone that smoothly!) I was originally wanting to go for the BeQuiet Dark Base Pro 900 Rev 2. Lots of space, lots of expansion, great reviews, plenty of space for ODDs (yes, I still use them, as I prefer buying music instead of streaming, same as movies) - but when going to get it from my usual supplier - was out of stock mad:) Emailed BeQuiet, and turns out they are replacing the case with something else later in Q2 2023 with less 5.25" bays than the Rev 2 had! So no stock of that case. Cue several hours of research to find an alternative and I manage to turn up the Define 7 XL from Fractal Design. Decent case, enough 5.25" bays for what I need, and plenty of room for everything else I have at present. Supplier A has stock, but I have to wait a few days for some money.... Damn went out of stock.... that's ok due to get some on 28/02/23, I'll place the order! Does it go smoothly... Nah of course not - no stock delivery arrives, and new ETA to supplier is now 24/03/23! Plan C.. Supplier B has it, for £40 more, and I have to pay for delivery as well Ah well, delivery to me is due on 02/03/2023 at some point during the day, so will be spending the day taking the rig apart and re-assembling and tidying all the cabling up in the new case. At least it will give me something to do and keep me out of the wife's way while she works from home!
Of course there's been another problem! Half way through the re-build and found some internal damage! A small metal bracket has been badly damaged and bent out of shape! Ordinarily I would not be too bothered, except in this instance, it has sheared quite badly, and has almost broken away, if I attempt to reshape it, it will brake off completely! I'm in touch with the suppliers to get it returned! I wouldn't mind, but I was almost at the point of getting everything wired up! nothing has gone smoothly with this build at all!
