This card is one I bought from ebay so not sure if I had any warranty, certainly not now anyway
Well I kind of just guessed really
Anything that looked like a capacitor or that it might contain a coil as I believe they are the main culprits for the whine
I was aiming to get the glue around and under the components. Originally didnâ€™t expect to get under but the glue thin and flowed and the components not that tight to the board. The theory is that by gluing them tight to the board they are much less able to vibrate. I actually had two goes a good few days apart that may have helped get more/thicker/stronger bond. Originally I glued the items on the power connector end only and replaced the stock cooler. The whine was much improved in my test bed PC with a Seasonic S12II-330 PSU. The PSU whined a bit too, difficult to tell how much from the card and how much from the PSU.
I read a post, supposedly from a video card engineer/designer, that the glue or nail polish can seriously shorten the components life, possibly due to overheating them by blocking air flow / holes. This seams unlikely to me given theyâ€™d have to be very small as I didnâ€™t notice any, but what do I know. Either way if you try anything like this consider the warranty voided and imminent fiery death likely
When I fitted the Akasa cooler etc I glued up the components again and the ones at the DVI connector end too. Used quite a bit of glue but as it was a 5 bottle pack from the Â£1 shop not a vast expense; nothing compared to the Akasa cooler and all the Enzotech heatsinks. (~Â£35 + Â£40 + the card @ Â£95 )
If the glue hadnâ€™t helped I was going to try more still and maybe something a bit thicker.
I tried it back in my main rig originally with the stock cooler, glued components and my modified NeoHE 430 PSU. It had had itâ€™s fan swapped and extras added to the heatsinks, thereâ€™s a thread about it.
The PSU whined rather a lot. It survived the first round of gluing but still whined pretty much as before. The second round I was trying gluing up the big coils with silicon sealant, I donâ€™t believe this caused the failure. I thought the PSU was drained (had tried to power PC with AC cord removed and get flash lights/fans etc draining the PSU) but I believe the cause of death was when I was scraping excess glue off the bottom of the circuit board there was a spark
Donâ€™t know what it did but PSU completely dead now, no output at all
Swapped another spare S12II-330 in my rig and it powered up fine. Whoâ€™d have thought a 330w PSU could run a Q9400 @ 3.2GHz and an overclocked GTX260
The S12 had some coil whine like the one in the test PC but with the noise of the stock cooler not very noticeable. Surprisingly donâ€™t think the PSU fan was noisy either.
Looked at PSU and tempted by Enermax Pro82+ 385w around Â£45 but put off by reports of the fans getting noisy after 6-12 months. I ended up getting Antec Signature 650w on special for Â£80 + shipping. With 5yr warranty Iâ€™m not going to mod it ever, probably
Had to mod the case a touch to get the 7â€
