Hey guys; My Specs: AMD ATHLON XP 2100+ 256K 266FSB SOCKET A RETAIL BOX 512MB PC2700 DDR333 SAMSUNG RAM ABITR9550-128CDT RADEON 9550 128MB DDR AGP8X WD 80GB 7200rpm hard drive SOLTEK KT400-A4 ATX SOCKET A DDR400 AGP4X 5PCI ATA133 USB2.0 W/SOUND I just ran Motherboard Moniter 5 and it shows that my CPU temperature is 55 degrees Celcius. Is that high? I have 3 fans installed in my PC, and I also have one fan already installed on heatsink of CPU, which came with it. I have this case, "NETLINK 18IN 350W ATX 3688 CASE /W FRONT USB PORT P4 READY". My two fans are installed back of the case which blow the air OUT, and one fan is installed infront of the case which blows air IN. here is the link of the case, "http://www.globalcomputersolutions.ca/catalog/product_info.php?cPath=1_38&products_id=116&osCsid=15e6dcd5e6065014ff1a895f9da17a2d" How can I decrease the temp. if it is too high? I have fan on the top of my video card, also. Is there any solution? I have reseated the CPU heat sink by using, "SILVER GREESE". My CPU temp used to be 65 degrees C, but after cleaning heatsink and fan it decreased to 55 degrees. If I do need to replace HeatSiNK which will fit my CPU................Is there difference between whether I get cheap or expensive heatsink? Also, is there anyway I can replace the front USP ports on this case, they don't work properly? Where to get them? Thanks guys.
