i have a 7800gtx sli set up with the heat pipe standard coolers on both and on everest it reports gpu2 5c hotter than gpu1 why? as ambient and gpu near same

see here

Motherboard 40 C (104 F)
CPU 42 C (108 F)
GPU1: GPU 40 C (104 F)
GPU1: GPU Diode 43 C (109 F)
GPU1: GPU Ambient 40 C (104 F)
GPU2: GPU 40 C (104 F)
GPU2: GPU Diode 48 C (118 F)
GPU2: GPU Ambient 41 C (106 F)
Maxtor 6L200S0 28 C (82 F)
Seagate ST380023AS 31 C (88 F)


can not understand is the diode faulty? or why is it running hotter? it use tobe basic level or gpu2 was 2-3c above gpu1

any info whould be helpful

thanks for reading neil

I think most here would agree gpu2 will always run hotter than 1. Why, I dunno tbh, but mine were 4-6c apart til I went to water, generally 1c or so apart now.

The only explanation I've been able to live with is my chipset is directly between my cards and puts out a fair amount of heat that affects gpu2 more than 1. I wouldn't worry with your temps.

thanks for that but why whould gpu2 be hotter if it is not the main system card only when running at sli mode .. i whould of thought the gpu1 whoud be a bit hotter as this is running system and gpu2 is idle

also i have a soundblaster card between both of them weired it is a a8n-sli board

Best I can answer is heat is able to escape gpu1 more easily while your chipsets heat along with the 2nd cards heat when enabled isn't gotten rid of so easily.

I could be wrong on that, maybe someone who knows more could jump in?:)

For me its the othe way around GPU 1 is always hotter than GPU 2:o

What motherboard? Doesn't at least one of the SLI motherboards (eVGA one maybe) have it so the 2nd slot is actually the primary. If that's the case for you, maybe that would explain it.

i have the A8N32-SLI and the top one (gpu1) is main one gpu2 now runs 3C above i cleaned filters

i do have a few dents on the heat pipe on gpu2 and how come everest says there running coller but the diode says other wise??

You could swap slots and see if you get the same readings, 2 hotter than 1. That would at least take any heatpipe damage out of the equation.
Why the 2 utilities are reporting differently, I don't know. I still think for stock cooling your temps don't look bad to me at all. My GT's idled around 40c for 1 and anywhere from 42c to 46c or so hotter for 2 on stock cooling.

yea i swapped them a bit back due too gpu2 was 9c hotter in the gpu1 slot so i have this setup how and get 3c hotter..

so it maybe the dents on heat pipe chould be throwing the temps ..

but everest still reports it being cooler and diode way off confused
