Thanks for this quick guide. That seemed to fix that issue. I've noticed on load the GPU fan speed can get noticeable when above 2600 rpm and fairly noisy at above 3200 rpm. Should I try to limit this? This may also be as a result of with how hot my card is getting too.
No problem. Hopefully we'll manage to sort it.
Yeah, I'd probably leave it as is for now, until we figure the rest out for you. But once we manage to figure your temps out, then you could try capping it and seeing how it affects temperatures. I did a lot of iteration, just trial and error.
So I pulled my thing open again, and I had my power cable going between the hdd and the fan like I mentioned before, it was not blocking the gap between the gpu and the hdd though the way I lined it. So I'm looking at how I should reroute the power cable. You mentioned wrapping it around the other end, but right now it just isn't long enough. It seems like I would have to pull out the optical drive and maybe even the HDD to undo a bunch of wiring so I can pull out the wiring for the power cable that is right now hooked through a hook at the bottom of the case and zip tied to the case next to the case fan. Are you suggesting to do all that so I can get some length on the cable? I didn't want to start even considering pulling all that apart without knowing for sure.
Here is how I have routed the graphics card cable (green is the right place, red is wrong for 7870 in my opinion, you need all that space by the fan).
Another question I had was how did you zip tie the gpu to the cage? I don't see anything at a glance that I can wrap around the GPU in order to secure it to the cage. Or did you do something more dramatic by having a zip tie completely go around the GPU and cage to pull it together?
Here is the picture of my cable tie and the graphics card:
Final question, I noticed that the natural state seems to have a small gap between the board of the GPU card and the cage. It's enough to run the power cord between the board and cage and go from the bottom of the GPU to the top where the power port is rather than going around the HDD. Is there a reason that I shouldn't try doing this instead?
I actually have never thought of this, but it sounds feasible and potentially beneficial. The only thing you want to look out for is that this doesn't push the card down so much that the card fans stop spinning. Best way to test this is to run Furmark, if the temperature rises uncontrollably just hit ESC when it passes 95C to abort.
Some other things that generally seem to improve temperatures, although not dramatically
- Horizontal position, device seems to get more air in
- Removing ODD in case you don't need it (this is just like a degree or two, I have mine in)
- Repaste of CPU, the default paste is crap and badly applied usually
Thanks again for all your help and advice so far. I'm probably going to just leave this apart until I can get a better understanding.
My pleasure, tinkering and optimizing is part of the fun for those who enjoy it (I didn't think I would, but did). It's fun to think of a small adjustment, do it and test what happens. My first weeks were more of that than playing
