Sorry for the delay in reporting friends. Once again there are good news and bad news!
The good news first:
I finally got a cooler for my Core i7 920 CPU, namely, Noctua NH-U12P, thanks to thunder.02dragon. The package included the backplate and all such accessorries for socket 1366 CPU, as well as two 120 mm fans for a push-pull configuration. I also purchased four CM 120 mm blue LED fans for the cabby. thunder.02dragon was so nice as to not only deliver the goods personally (as he has done before), but also to spend considerable time in installing the cooler and all the fans for me, which involved some re-routing of cables and shuffling/swapping two fans that came with my CM Cosmos S 1100 cabby. This guy is a totally different breed compared to the other run-of-the-mill vendors I know and I shall give two thumbs up for his dealings with customers and request you all to seriously promote him.
After keeping me hanging for nearly six weeks, LG finally fixed the HDMI problem of my new monitor (L245WP-BN). They say that they had to replace the PCB with the latest one and everything seems to be working fine right now. However, there's a catch and that is part of the bad news!
Now the bad news:
LG took away my monitor for the repair, missing one Wednesday in picking it up and another in its delivery, making me wait for a total of three weeks, blind as a bat without any monitor. This is in addition to the three weeks they took in just figuring out what's wrong with the monitor! However the worst part is that the monitor came back with the display panel SCRATCHED ! They have agreed to replace that too, but two weeks have passed since then without any progress in that direction! The frame has been scratched too but, though easily visible, it is not an ugly scratch and I am willing to live with it. It seems they do not know how to handle a delicate thing like an LCD panel. At my home they unceremoniously dumped it face down on a surface with plenty of dust on it. It is only on my immediate and loud protests that they allowed me to spread out something clean. Only God knows how they handled it in their workshop! No wonder, therefore, that the display panel is scatched.
The other bad news is that, as has been suspected by me all along, the CPU cooler clashed with the 200 mm fan on the left panel of my cabby. Hence there was no immediately available alternative but to remove the 200 mm fan. thunder.02dragon suggested a substitute fan panel that can accommodate up to four 120 mm fans, but we could not locate it in the market immediately. thunder.02dragon has promised to keep an eye open for it and I am going to get it if and when it is available. Till then my system's ventilation is not quite balanced I am sure. Please let me know if any of the forum members knows any other solution.
