Can anyone suggest a cooler/heatsink/fan combination for a Geforce 7800GT? The two after market coolers I bought wouldn't fit (apparently the architecture on a 7800GTX is different than a 7800GT). After reseating the stock cooler, Speedfan is reporting idle temps of 79 C and after 10 minutes of gaming, it's reporting 109 C! I don't have a lot of space in my case, but I can move my wireless card down one PCIE slot to give extra room. Help!
