Hi onemilimeter
1. Are there any noises still from the MB's CPU area?
2. How it's possible that you informed OCZ through their forum that "it's confirmed the noise is coming from the PSU" more than a month ago while at our forum you claimed the noise comes from the MB since the very beginning of your posts - here (24 May) till last Fri (above quoted)?
3. How was the RMA process of your OCZ PSU?
Hi...
[R1] I can't confirm if there is ZERO noise from the MB's CPU area because the PSU fan noise is still relatively loud.
[R2] Wow... you can remember better than me... Initially, I thought my noise problem was due to MB. That's why I posted in TT forum (before I knew about forum.giga-byte.co.uk). At TT forum, I was somehow convinced that it's due to my OCZ PSU. Then, I posted a question at OCZ PSU. I didn't take out the PSU to check but used a "straw" (suggested by an online user) to identify the noise source, so the identification may be wrong. After following dkslim's thread, I started to believe again it's due to the MB because (1) the noise pattern responses to different settings in BIOS, (2) many users with other decent PSU brands have reported the similar issue. Then, lately, I found out my noise problem is very similar to the dkslim's case. Well, I'm not a computer expert, let alone the design of the motherboard and the PSU. If you follow my posts in dkslim's thread, it's not difficult to find out some of my earlier comments or findings are not correct. Like many other forumers who follow this thread, I learn and try to understand the problem bit-by-bit ourselves especially at earlier stage when Gigabyte was quite quiet. What can you expect from forumers who do not have decent tools or equipments like in Gigabyte HQ or RMA center to troubleshoot the problem? Well, Gigabyte Australian, like dkslim said, has identified the problem and dkslim has described their findings. Again, it's quite clear that, at least at the moment, the source of the noise problem is the motherboard itself and not the PSU. So, Gigabyte should focus on why their motherboards cause the PSU to make noise and not trying to go around the internet and see what the forumer has posted.
[R3] I do not proceed the RMA of my PSU because (1) need to send to the Netherlands, (2) the replacement (as claimed by many) will have the same problem, i.e. the fan controller is quite sensitive to temperature variation and the fan will spin at high speed when I put the PSU back into my cheap computer case which has poor air flow.
