The main things I'm going to test are 1) Balancing CFM in vs CFM out and 2) removing the intake fans altogether and just having exhaust fans...There are a lot of tests that point to #2 as being the best cooling solution

I tested #2 today on my Q6600 running at stock speeds

My original fan configuration is 2 120mm 63cfm scythe fans in the front (sucking air in, everything else is exhausting air out of the case), a 92mm 38cfm fan in the drive bay, and 3 mini kaze 4.8cfm fans above the i/o ports. CPU temps climbed to 62 degrees and held there under constant load. With both side panels off, temps only climbed to 51 degrees and held there. Of note, my power supply is not a bottom feeder, so I don't think it will help with extracting any heat from the cpu area (I did this on purpose so that the fan I'll put on my TR won't compete for air).

I first modified my original configuration by simply removing the 2 120mm scythe fans from the front of the rig. Leaving everything else the same (only exhaust) and screwing the side panels back on, temperatures exceeded 67 degrees and were still climbing...I stopped the test. It took about 10 minutes or so for cpu temps to come back down to idle temps.

Not happy with those results, I replaced the 3 mini kaze with 3 Silenx 40mm 6cfm fans, and added an additional 3 Silenx 40mm 6cfm fans to the cpu vent. All fans, again, were set for exhausting hot air out of the case. This time, temps matched and behaved exactly like my original configuration.

That's as far as I got. I think the key was placing the fans near the cpu. My next test will be matching cfm in to cfm out (basically, I'll just put the original lian-li fans back in the front and leave everything else the same). Then I'll try placing the the scythe fans in the front again to see what happens. My guess at this point is that I'll see a further temperature drop under load when I add the Lian-li fans back in the case. I'd also guess, based on what I've read so far, that the temps will rise again if I put the scythes back in (pushing more air in than the case can expel).

I'll let you know how it goes. More testing tomorrow!
 
Added the stock lian-li fans back in. (LI121225BL-4). When looking up the specs on those fans again, I found that they have a cfm about 56, not 38 as I originally thought. So positive pressure is being created as I have the two 56 cfm fans in the front about 36-38 cfm exhaust in the cpu area and in the drive cage area.

Under load, core temp is reporting a steady 60 degrees, which is only a few degree drop from my original configuration. I think the cpu fans help, but are two small to really drop the temperature more significantly. When switching to idle mode, the cpu temps drop a little faster too (It takes about 2 minutes vs 4 minutes to get back to original idle temps of 38 degrees).

At this point, I don't feel that placing 63 cfm fans in the case (vs the 56 cfm front intake fans) will produce any significant differences. I'll have to decide if a 9 degree difference under load is worth cutting a hole in the side of the case (similar to the pc-v300). After placing my TR on there and looking at temps, I'll have a better picture I think.

Has anyone else cut a fan hole there? Did it help? My guess is that it would help significantly. If three small 6 cfm fans made a dent, I think one 80/92/100/120 mm fan would for certain.
 
I'm planning on a building a rig for my mom in this case and I have a PC Power and Cooling Silencer 500w I want to use think it smart to use that PSU because it doesn't have a 120mm fan.
 
I have the 750w version of that PSU. All I can say is, it depends.

If you were looking for something to help exhaust hot air from cpu area of the case, it won't help. But it does keep itself cool. I personally like having the 80mm fan sucking the air out of the PSU. Everything I've read says that's better than trying to push hot air up and out of the PSU from the bottom.

Another consideration is what you are going to use for a heat sink. I went with this psu specifically because it was rated well for supporting sli/crossfire, and because I have a fan that is blowing down over my cpu, a configuration that wouldn't work well with a PSU that has a 120mm intake fan right above it.

I'm putting the 750w silencer in my tower when i start it again. :d
 
im considering buying this case, would you guys say a ninja mini and a q6600 would fit nicely in their? i currently have an nsk2480, and its to big for my liking.

I'm running a Ninja Mini on a e8400 and DFI LP JR and it all fits just fine.
 
@rainfall...i replaced the normal connectors with and IDC connector..
DSC00668-1.jpg


going to replace my 4870..because of heat and driver issue, my v350 wont run stable with this kind of card..might go back to nvidia..
 
anybody knows how to open the front cover of this case? i just want to screw my optical drive on the other side properly. thanks
 
grabshell, its not easy mate..you need to remove the HDD tray to unlock the middle screw behind the front panel
by doing this you need a drill to remove those rivets..ive done that and replaced the rivets with screws..

your v350 should be look like this after removing the tray..,:)

2Red, what are you using for the replacement plate there?

Wanted to do the same thing, but I was having trouble finding a decent piece of aluminum that I could cut. Either too thick, or too small locally.

That pre-perforated looks GREAT though.
 
Hi Guys i have a question, which heatsink of xigmatek of similar fit on the v350 I wonder that I have a noctua c12p mounted on a lan party jrp45 but the socket is very on the edge then I can not get out the motherboard tray with the noctua mounted, so i am searching for a 92 m tower any idea ? Thanks !!
 
Stupid questions deserve whatever answers they get. There's a picture of it fitting and you ask if it can fit?

I was not sure whether it was a noctua I just wanted confirmation and your good models needs to learn how to treat people ...
 
i got my build into this case, and well so far, its pretty loud, louder than my nsk2480 but i can switch the fans later. the cpu also gets hot, im running 42c idle core0 on a q6600 when i had 36c idle on the nsk, this is on the stock hsf though, and yea i know its a smaller case.

to me its worth it, since its so small and nice looking, i just need to put some more money into it.

Post load temp when you talk about temperatures.

thats the thing im afraid loading the cpu will go over 60c, but ill try it in a bit, keep in mind i have the AC on and my house is cold.

the fans are also loud, so what kind of fans would you guys recommend for this case? id like decent air flow and for them to be quieter than the included ones, and is the 80mm exhaust fan really needed?

as for HSF, im going for a ninja mini, any other HSF's out there around same price range?
 
just primed my cpu,keep in mind everything is on stock settings, and so is the HSF. my temps reached 70c and i decided to pull the plug, im sure it would have gone higher to.

I just got the Thermalright SI-128 SE and I'm using Scythe's low profile 100 fan (12mm thick). I'm getting much better temps than the stock cooler. Since I can't hear that fan, I leave at it's max speed. I did this when using the Scythe Shuriken HSF as well (nice if you are not going to O/C as it's very low profile and you can still slide your mobo tray out with all components installed).

Here is a link to some pics of my setup (I have to get the latest up there soon). Anyway, you can see how the AC Freezer 7 Pro did *not* fit, and how the Shuriken does fit.

I tried various things to cool the case down. My next project will be to cut holes for two 60MM fans where I have the 3 40mm fans (Preserves the look of the case while adding much needed venting of the cpu area).
 
are you OCIng? i was maybe looking to get my q6600 a decent OC to maybe 3ghz, but of course HSF is limiting me, you think that id be able to achieve that on the SI-128? ill also look into that scythe fan since its quiet.
 
Now that I have the SI-128 SE in there, I will begin overclocking this week. I looked at the mini ninja reviews and this one is better. The only other one I would consider for this case would be the Noctua NHU9B. I'm hoping to get a 3ghz overclock and I think this is the heatsink to accomplish that with my rig.

This will be my first overclock attempt, so I'm reading up and trying to understand the methodology behind it (read: it might take me a few days to figure this out and a week or two to get the best results). The q6600 is very hot, so while I'm OCing, I'll be leaving the side panel off the case (processor side) until I resolve my heat issue I mentioned in previous posts.

Also, for reference with the side panel off and using the scythe shuriken my 3d marks and temps were as follows (at stock speeds):

3D Marks and Temps at stock speeds (2.4 Ghz cpu)
16218 3DMark05
13470 3DMark06

Temps on my video cards maxed at around 50C (thanks to those large heat sinks)
Temps on my q6600 maxed at around 50C (side panel off. With the side panel on, it was 10 degrees hotter, due to the hot air in that section being recycled instead of exhausted)
Northbridge was the same 50C

im running the g45 board from gigabyte and im using the IGP since i dont game, here are my temps:

these are side panel on temps:

q6600: idles @ 42c / load: exceeds 70c so i killed the switch.

NB: 29-30c, goes back and forth, interesting that the p45 nb is hotter than a g45 when using the IGP.
 
Doesn't surprise me too much, given that I have two, relatively powerful, graphics processors vs the one integrated processor. When putting those processors through their paces I'll have a lot more traffic going through the north bridge.

What are your "side panel off" temps?

here are my temps (w/side panel off) with every imaginable temp monitoring software lol. basically 37-34-34-31 across the cores.

also, i dont know why real temp confuses the 3rd and 4th temps, it always has them mixed up.
