How many yrs warranty do your drives come? You can find it from Seagate website using the SN of your drive. My 410AS comes with 5year warranty. I am afraid that Seagate changed warranty to 3yrs for 418AS.
My Q6600 running at 3Ghz, full load temps for four cores are no higher than 49C with Xigmatek S1283 installed, and 59C with the Intel stock cooler. I would check the contact of the heatsink and processor first. Your temp looks too high to me.
The ASUS and Gigabyte are Taiwan companys. The are best motherboard manufactures. My EVGA vedio card and seagate HD are made in China. MY HP and DELL laptops are made in China too. All them are working perfectly well. Stop posting craps please....
