Hi Guys,

I was just wondering if some one would be able to confirm if my 680s fans are running at 4000RPM is that a bad sign of air flow or is that just normal for 680s to run that high speed (it gets kinda loud)? They have no OC and the max temp one of them it is 81c and the other is 65c.

Cheers
 
Yeah they are both together... problem is that my psu is at the bottom of the case so there is no room to put the second card on the third pci slot... Will this cause problems with the cards? Or should I try moving the psu around?
 
This is one of the things that get over looked when going SLI. The noise is horrendous and I would strongly advise anyone considering SLI/Crossfire to put them under water. If water is a 'no no', then I would always recommend a ref style card for the bottom.

Those temps are normal sadly because the lack of air between the cards is making it worse.
 
Yeah I was hoping to wait for the new Haswell CPUs to come out before upgrading my mobo. Ill stick up a photo of inside my system either tonight or at the weekend, to show the problem more. Its mostly the problem of the PSU being at the bottom of the case and is blocking the third pci slot.

That makes sense. I use a NZXT switch case, which allows me to use any PCI-E slot and still have masses of room below for the PSU.

That pic is probably the best way I can show how the case helps but make sure you are not switching down to X4 on your lower PCI-E slot.
 
Great looking PC you got there :D What do you mean by 'make sure you are not switching down to X4 on your lower PCI-E slot.' not sure what X4 is :)
 
What motherboard do you have BORG? Sometimes if spacing is tight, placing a fan behind the cards can help drop temps a bit. On my old 470 sli setup, an antec spotcool placed behind the cards helped drop 10c of the top one.

Cheers.

My PCI-E lanes that are used are x16 and x16 (both running at x16) with Z77/Z68 boards, some will run at x8 and x8 and the last slot can be x4.

What mobo is it and I will let you know is the best answer I can give :)
 
The bottom slot is X16 I believe on that board, so a case would do the trick :)

Edit:

I am wrong, the bottom PCI-E runs at x4, so that would hinder performance (not by much).

Spacing on the sabretooth x58 is a bit tight compared to the older p6t deluxe v2 i had in the pic above. I had a similair problem with a p6 x58de in my current 2nd rig. Spacing on it is identical to the sabretooth. And the bottom slot is x4 so this cant be used for sli.

P6 x58de with sli 460's.

Id try a fan behind the cards, preferably something with high focused airflow. The silverstone air penetrator fans are good for this kind of thing. Or alternatively, the Antec spotcool if you can mount it easily in your case.
 
For now ill look at getting some new fans I have free space for a side fan on my case that should hit directly on the gfx cards and ill also get one of the antec spotcool. I think ill wait a few months to see what Haswell brings and then think about CPU, Motherboard and Case upgrade. Which Cases would you recommend now? If I do choose to upgrade sooner than later.
 
I dunno if they are made to run high all the time 24/7 they will wear out like anything.

This is why its best to take all this into mind before going for things like Sli.

Like mentioned try sticking a fan inside id rather pay £40ish for a fan then bork a 680 :)
