This is an FYI for anyone who is still using an old Vostro 230 with an LGA 775/771 CPU and stock G41 motherboard. I just wanted to share my experience with a cooler that I purchased to have a quieter and cooler computer for web surfing and document creation. I just purchased a Jonsbo CR1400 92mm cooler and it bolted right into the stock CPU backplate with no modification and no issues whatsoever. The 4 pin power for the fan also did not create a boot issue like some I have seen with various dells. This cooler is a plug and play product and was a breeze to install. I previously modified my socket to accept an Intel Xeon X5460 3.16Ghz Quad-Core with a 120W TDP and flashed a modded BIOS with the Xeon micro codes. So, I needed a better cooler. I was also able to get it to accept 2x4gb ddr3 low density Crucial modules. It has a 250GB Samsung 860 EVO SSD boot drive, 250GB Seagate mechanical drive, and a Sapphire R7-370 4GB graphics card. I also installed a new EVGA 80 Plus 600W PSU.  I am typing from it right now. I looked for a definitive answer as to what specific cooler would work with the stock CPU backplate, but was never satisfied with any of the answers given on lots of different sites. I figured if I am doing this, then somebody else might benefit from my experience. I created this account solely to share this with others that might be interested in doing the same. I hope this helps someone out there wondering.
