I'm planning to build a new machine and I'm thinking of going WC for the noise (primary) and the temperature (secondary) reasons.
It's going to be my first WC build, I've been reading reviews for about a month already but I still fill a bit lost
So the hardware I'm planning to get:
cpu: i7 3820k
mb: Rampage IV (formula or extreme)
graphics: one or two GTX 680 (as soon as they become available)
power: Corsair AX850
So the questions:
- Is it a sane WC configuration? Is it an overkill?
- I get that it should be more than enough to cool the CPU only, but what about CPU+one GPU? CPU+two GPUs? Do I need one more rad? (skinneelabs says it can dissipate 600w)
- What case would be a good fit? I've read some good reviews on Obsidian 800D... but it seems folks have different opinions on that..
I would go with mpc 655 pump the apogee hd water block an xspc double pass 120 x 480 any rez will do and place it in an tj07 silverstone all internal.. i built one and did vid on youtube under robustus64 check it out.. its cooling 2 x 480 and a 3930 @ 4,8 ghz cpu never gets above 61c gaming..
The 35X would be my pump of choice. It has a higher pressure rating so you'll be able to run more components with better flow. The MCP655 isn't bad (using one as I write) but considering you can pick up a 35X from Jab-Tech for the same price I paid for my 655 Vario, it's a steal.
I feel like a single rad won't be enough, especially since you want to cut back on noise. You're looking at ~600W of heat generation in the loop, so I would look for 2 good 360 rads that can dissipate 300+W with quieter fans (~2000 RPM). The XSPC RX rads are very good in that area since they have a lower FPI count.
I second the MountainMods and Caselabs cases. They look fantastic and can really be built to you specs/needs/wants.
wrt TDP calculations:
i7 3930K (stock) = 130W
i7 3930k (OC/4.5G) = 250W
GTX 680 (stock) = 190W
GTX 680 (OC, didn't find numbers) = 220W (approx)
I don't think I ever need both at 100%, so 2 GTX680 + OC CPU roughly translates to 550-600W. Does that sound right?
wrt Reservoirs: I didn't see decent comparisons for reservoirs.. I saw a post on the Martin's website, when he got good results even with MCP35X Reservoir top. Are there any well-known good res's out there?
wrt CPU blocks: Looks like XSPC RayStorm is comparable to Apogee XD, but all reviews say Apogee has much nicer and better mounting. It also has 2x restriction comparing to XSPC RayStorm How bad is it?
And speaking about pressure. According to my (completely amateur) calculations:
MCP35X + Apogee HD + 2 * MCW82 GPU blocks + 2 MCR320-QP = ~1.2GPM
MCP35X + XSPC RayStorm + 2 * MCW82 GPU blocks + 2 HWLabs GTX 360 = ~1.2GPM
Does that sound right? And how good is that flow?
low restriction, good mounting and material choice determine how well a block will perform. since the HD has a good contact patch, better than all the blocks compared it trades blows with other blocks that have reduced contact. so you understand now, why the HD is a good perform inspite of having higher restriction?
you could also look at the DT 5Noz...but is pricier
rads, the heat source is what is different from these tests, have you also noticed the ambient temps of both test procedures?
the other memebers can point out whats cooking with the two dif tests results+blocks
