I wasn't sure if to start a new thread for this? Well I haven't so I hope that's ok.
I've just got my Sonata case today and have fitted everything. When I first switched it in I couldn't believe how loud it was! After a short time the PSU slowed down the fans, and Q-Fan (Asus BIOS) slowed the CPU down and that all helped a lot.
However, it really isn't anywhere near quiet enough to sleep in the same room as, which is my aim. I've got a Zalman Fan Mate 1 on order which I plan to fit on the CPU fan (stock Intel) to make it even slower because Q-Fan only brings the voltage down to 8V. I'm also wondering if I should spend even more money that I already have, and buy a large heatsink for my Sapphire Radeon 9000 PRO graphics card, as that fan is probably part of the noise.
So what else can I do after that? I think I can get a heatsink for the graphics card for about £15 (I'm in the UK) and if spending that is going to help a lot, I'll do it. I've tried to find out if that particular heatsink is going to provide enough cooling but there isn't much said about it on the Internet. I can't even remember the make and model at the moment, but it's several copper strips stretching about the length of the card or maybe a little more, so I would have thought it would be sufficient.
I already have a Seagate Barracuda 7200.7 HDD which is very quiet and although I could here it seeking on my old case, I can't even hear that now so that's great. I have an IBM 20.5 HDD too but I only use that as a backup, so the loud seek noise it puts out won't be a problem. I don't know how loud it is just from spinning but I don't think it's going to be a problem.
So do you guys think I'm going to make the whole setup a lot quieter by loosing the graphics card fan and slowing the CPU fan down a bit? Is there anything else I can do without spending too much more?
By the way, I've looked into another heatsinks/fans for the CPU and it looks like the Intel fan is already one of the quietest. I don't overclock, at least not at the moment, so I don't care about a different heatsink. I'm sure I could already make the fan go as slow as it will without stopping and the temperature will still be fine, so I see no point in changing that fan.
One point about the Sonata for other UK people thinking of buying one. Mine doesn't have the 4-pin Molex type connector on the back of the PSU (outside of case) although in the reviews they say it does. It doesn't matter to me, but in case it does to someone else, bare that in mind.
