I have an Asus V6600 pure w/SGRAM video card and use a OEM Intel P3 flip chip HSF instead of the one that came stock with it. I used super glue to attach it to the GPU and used thermal grease between the two. This setup has worked very well for a number of months to keep the cards temps below 38 to 40 Cel. even under load. However, now the cards temps stay closer to 48 to 50 Cel. at idle. And rise to 135 degrees F. Unsure at temp in Cel. ? Fan is installed and running fine on card. HSF appears to remain correctly attached with no visible gaps appearing. HSF was also lapped before installing on card. Why is it running so hot, case has lots of cooling. 3 fans mounted on side of case, two blowing on video card, one blows on CPU, also have one 3" 6500 rpm fan used to exhaust air from case. Do I need to reinstall HSF or will the problem just reappear with time if I do.
