Letting FC3 idle a while at 1200/1700 got to 66c core, 99c vrm1, 85c vrm2 @ 60% fan speed. [Took out my small VRM fan for this test]
So I turned it over...
and first the temperatures went down about 2 degrees on everything.. then out of the blue the VRM temps skyrocketed and the core temp went up to 72c and then the display driver crashed. The core overheating didnt surprise me -- its the VRMs... why? They have no form of cooling that is effected by orientation...? And if its the air temp, it wouldnt respond to it increasing so quickly. Too bad, as this case looks so much better in the proper orientation xD
I asked sapphire about the heatpipes they use -- it is Groove based. After asking if they would consider using powder based heatsinks for people with 90* motherboards, they said they'd relay it to their cooling engineers.
I also asked about the 8+8 pin vapor-x. Apparently it has a majorly improved cooler versus the old 8+6 pin card.
I got the 8+8 pin vapor-x and the cooler seems to bemuch better that yours according to temps. Here is my post from the 79xx overclocking thread:
I got my 7950 Sapphire Vapor-X with boost the 8+8 pin power edition a few months ago and until ysterday i just ran with boost bios and 1100 mhz core since i did not need anymore power. Decided to try Sapphire trixx 4.6.0 today and see what this can. Alse been readig alot about some people having bad VRM temps, but my card have been running with very fine temps all along.
Today i tested the first speed with 1.165 mhz core and 1.400 mhz ram (not interested in max ram speed atm, finding core first). VDDC was set to 1,25 in trixx and under load it drops to 1,176.
My maks temps when playing BF3 with all on ultra settings and max Antialising was following.
Fan auto control: max speed it hitted was 46%
gpu temp maks: 59.
VRM 1: 65
VRM 2: 62
I use a Lian Li PC-71 cabi that have 2 fans on aech side of the hd which also gives some ait to my gfx.
I took a screenshot at maks temps today under 100% load in bf3. Link here: https://dl.dropbox.com/u/24980537/BF3%20maks%20setting%201165-1400.jpg
So far i am very pleased with this card. Very silent and should be able to hit 1.200 on core hopefully without probz.
