What To Buy???? - Page 2

post #11 of 18
my 745 with stock fans keeps my overclocked sandy @2915mhz (265X11) 1.5 vcore, 2.85 vdimm @24c idle 34C Load ambient 23c . What is your ambient temps, that will effect how cool your water will be. @ 3003mhz (273X11) the temp doesnt change, but my ram gives up after an hour of prime @ the 333 divider .

Edit , i keep forgeting i have removed the lid off my cpu , with the IHS on my temps were never above 40c load .

I don't mind at all.

I'm just burning the system in, and have not overclocked. At stock clock with stock HSF I was getting 36C idle, 52C at 100% CPU utilization (one instance of Prime95 running on each of the two CPUs).

Without curing my AS5, I am now seeing 34C idle, 45C load--and this is with the BigWater cooling both CPU and GPU, and the low-flow fans running in silence.

I suggest you get a fan controller, and vary the speed of your fans under load. I'll bet you can turn them way down with minimal temp rise.

Hope this helps.

Agreed. For what it's worth, SilentPCReview found the Nexus quietest, and they are quite anal about these things.

It's irrelevant, but I find a silent fan with the name ThunderBlades ironic.

Hope this helps.

The lack of a fan controller on the 745's larger radiator was one of the thing i didnt like , the smaller radiator does have one thou .



DrDeville, which water block are you using for ur 7800? Im just cooling the cpu , and would like to put the gpu into the loop. The only thing i was concerned about is the ram , some of the water blocks ive seen just go over the gpu core , and leave the ram uncooled. Thx Rukkee

my ambient temps are usually anywhere from 30-34c, my panaflo fans came today. they are so huge they are at least 1.5x thicker than the thermaltake.

Hi Rukkee,

I faced the same decision as you, and decided to water-cool the GPU only. The GPU+Ramsink waterblocks are nicer, but can only be used on one model card, and cost at least $100, from what I saw.

So I went with the Thermatalke CL-W0038 Aquarius Series VGA Water Block. It was well finished on the bottom, and seems to work well, but I don't like its flimsy mount for my 7800 GT. It's snug and horizontal, but has some lateral play, which bugs me. I think I'll be able to mod it to fix this, but if I had it to do over, I'd at least consider something else.

Regarding ram, I added some spiffy Swiftech copper ramsinks, which I expect will work fine in my case, which is now cool as a cucumber. The thermal tape on the Swiftech isn't holding them on, so I've got to figure out another thermal adhesive that will hold them on, but let me remove them if I want to change something.

Being a perfectionist isn't easy.

Hope this helps, and have fun!
