Hi Guys

I have a cooling issue on my new machine and after some advice.

My case I know is not the best for cooling but I love it and it was expensive so would like to avoid changing it if possible. I will post the specs below but first the issue.

I have a Corsair H50 watercooler on my stock clocked I7 930, idle is around 38C and with Prime 95 I switch it off before it hits 70C so no idea how hot it goes.

The H50 is using the stock corsair fan and is in a Pull configuration venting air out the back of the case, front fans pull air into the case, top fan pulls air out.

I have read about the push-pull config but where can I get screws that will fit through the fan with enough thread to bite into the Rad holes? Also I must have not done everything right as sureley even stock I should be seeing better temps under load? Should I try refitting it and also using better paste (reccomendations?).

So thats issue 1, issue two is that I have 2 x Pallit GTX460 1Gb Sonic cards in SLI. Now the clearence between the cards is pitiful, maybe 2mm between the top cards fan and the bottom cards PCB. Now they overheat under load, using furmark I cancelled the test once the top card hit 83C (and still rising). I guess I could watercool the cards but I would need an external system, and I think the issue would be the water fittings on the cards GPU block, even if it works it would be expensive (tho I would like).

Another option I guess is to fix the H50 issue and then fit way more powerful fans in the case, but then I get the issue of noise and may not be that effective.

Next idea is to change case :(.

Any advice much appreciated.

Spec:
Asus P6X58D-E
12Gb Corsair XMS3 Ram
I7 930 CPU
4 1TB HDD's at front of case.
2 X Pallit GTX 460 1GB Sonic (Factory OC)

Thanks

70 degrees isn't hot for a 930, unless that's at stock speeds off course. You might get better results with push on the H50 rather than pull. Push/Pull will not affect your temps more than a few degrees.

83 degrees on a 460 is not that bad. I dont have a 460 but I hear they are toasty cards just like the rest if Fermi. Any way you can separate the two graphics cards so they aren't lying next to one another?
 
Hiya

Yeht he CPU is stock, but tried again tonight and the cpu maxed out at 66c, I think i will upgrade the fan on the Rad and reseat with arctic silver 5.

The gfx cards are awkward because there is my Xonar on top, 5mm below is GFX card 1, and 2mm below that is GFX card 2.

Now I may try moving the xonar to the far bottom slot. No way to move the gfx cards cos they are in the only x16 slots on the board & the sli bridge is not long enough for them to be further apart.

May try a more powerful 140mm fan on the top of the case aswell.

I noticed Lian Li do a lot of sidepanels with fans available seperatley, but they do not say which if any will fit my case.

Thanks

I have 2 msi cyclone in sli. The top one gets so hot and noisy when gaming! My motherboard is the asus P6X58D-E aswell, they both sit so close together the top on can hardly breath, the bottom one is about 25c cooler in gaming than the top one. They are both overclocked to a respectable 810mhz core and 950 memory with no change to the voltage. Right now with the side panel off my case and an ambient temperature of around 20c. Top card idle: 45c Bottom card:31c, did a just cause 2 benchmark and the top card went to around 87c Bottom car 60c that was only a few minutes!! If i game for a few hours it will probably explode and send me deaf in the proccess. I have also switched the cards around with the top one always having the same temperature difference. I was thinking of using the bottom pci slot on the motherboard although according to the manual it is x8 link, i looked in the bios but couldnt seem to change it. Well if anyone can help i would much appreciate it, oh yes i also have the latest drivers installed and according to nvidia control panel sli is working fine, maybe there are some steps that i could do to sort this out. Thanks!

You can buy a longer sli bridge of ebay, thats what i am going to do. Also what are the clocks of your card? Have you tested with the card in the lower slot, i will be today and will report my results. this will be without the longer sli bridge which i should have early next week.
 
Try reversing your airflow so the H50 gets cool air from outside the case not hot air from the GPUs. You also need to reverse the front fan to exhaust. I think this is how corsair recommend to do it.
 
heelo
dont no if people have mentioned this but your cards will get a lot hotter than that. can go to 105C so that not a problem at all

with your H50 you want the air sucking from out side of your case blowing threw the rad and into your case

also you can get screws for you push/pull form b&q and where that sell screw there nothing special just take the ones you got and get the smae
 
Well I did a bit of work today, I changed the top 140mm fan to a be quiet silent wings, and added 2 akasa vipers in a push pull config (still exhasuting out the back) and used some arctic 5.

Temp on idel CPU is now 29C and 59C under 100% load

For the gfx card I moved my xonar from just above the top GFX card to below and GFX card now max's out at 85C.

I am also looking into a side panel with fan to extract straight from the top of the GFX cards.

Will also try reversing the H50 and front panel fans.


Thanks

Heya

Im pull air in over the rad as suggested, I also have a side window that can take a fan which sits just above the gpu's, question is do 460's suck air in or vent through the back of the case?
