The Official PC building thread -3rd Edition

lol. No, thank you!

 

All tests I have seen showed no loss in performance due to high water flow, although there is virtually no benefit past 2gpm. The problem usually is that with more powerful pumps the small gain in increased flow isn't offset by the larger heat dump from the motor. See here for more information.

 

Red_Maw,
Nice Spreadsheet, but very flawed! There's no information as the Ambient temperatures, and no indication if those temps were altered for more real world numbers. I'm not saying that he is right or wrong in his conclusions, but that the manor in which the tests were conducted doesn't contain near enough information to draw a proper conclusion.

You mentioned no loss of performance?? What performance would that be? If the room is 55F, like Anandtech and others set their temps to review CPU coolers, you wind up with very close performance from Brand to Brand, Kick the room temp up to a more normal 78-80F, and it will better show you which models cool the best! Separate the Men from the Boys, so to speak!

I also don't see the possibility of a larger heat dump from the motor. The pump motor only draws 1w, and spins on ceramic Bearings, so there's no lubricant required, and almost no friction.

After seeing that 6 core AMD overclocked to 4GHz, and the temps they recorded with the CoolIt, I'm about 95% convinced to buy one!

If I bought this and want to add an extra fan, what would ya'all recommend

CoolIT SYSTEMS ECO-R120 Water Cooler

Rick,

Plug it in to the system header of your motherboard and it should run both cool and quiet!

Best Regards,
Russ

 

the cores would be amazing for your encoding russ, do it

though what would happen to the 955?


btw can someone build this for me?

I imagine most encoders may not know how to use 6 cores. CCE is industry leading though, So I guess it wouldn't surprise me. And I imagine programmers may already be on 6 and 12 core capabilities for megui, ripbot264, etc Might be a bit early for buying a 6 core cpu, but not TOO early

Shaff, what the heck is that! LOL!

 

Oman7,
I believe that CCE can handle any number of cores, so 6 cores would probably put encoding in the low to mid teens on average. Good lord, I remember three hours or more! ROFLMAO!! Set it to run and go to bed! LOL!! Oh and hope you don't wake up to an error! LOL!!

Russ

 

I'm not a programmer, but there is a certain logic to a scalability within a program. What I mean is, the number of cores SHOULD be negligible/pointless. One day, I'll understand how stuff like that works I think about programming a significant portion of my day. I might even understand in my own way, how a lot of it works. As I said, there's a certain logic to it all. Math is everywhere...

 

Haha stupid moment. Was running IBT today when my motherboard speaker starts throwing up the alarm. I'm freaking out now. Is it voltage? Memory failure? After 20 minutes checking my settings over and over it finally dawns on me. Doi. Look in my BIOS and sure enough, forgotten I had set the board temp warning at 60*C for my Crysis testing. Well set the warning back up to 70 and all is peachy.

My chipset usually gets about 55-58 playing most games. But the system hogs, Crysis and IBT included, seem to push it a bit further and it gets into the ~65-68 range. All things considered not bad or dangerous. Will go up to video card-like temps before things get damaged. But I'm looking into some sort of aftermarket cooling for it... Just FTR never seen it hit 70...


Anyhoo any suggestions for aftermarket chipset cooling or possibly a small, low-noise fan?

 

I believe Enzotech provides some nice little aftermarket coolers for chipsets.

Antec makes a little fan that is nice as well... Russ knows which one it is.

there are some others but this is a good one. Antec 76005 40mm

 

Found a temporary/permanent solution for this. Got a 60 x 25mm Sunon from an old PSU(actually very quiet) hanging under the CPU HSF blowing towards the chipset heatsink. Produces reasonable airflow too. Dropped my temps a cool 10*C

Dunno if I'll use this forever but it works and it's quiet so fine for now...

Might look into a whole new aftermarket sink later but this fixed me up perfectly.

These are about as good as you can get.

GM,
That be the right fan! I have tried all of the others, and this is the only quiet and reliable fan I've found. 6.5cfm seems to work real well for chipset cooling. Buying any other 40mm fan, is just a waste of money, because they don't last out their warranty!

The big problem today is all those heatpipe coolers that come on a lot of the newer motherboards. Most have two parts joined by a pipe. Some even have a third, for the Southbridge. They all have to come out in one piece. Mine covers the NB and the VRMs, behind the CPU cooler. I took those pretty blue aluminum covers off both heatsinks, and put a more powerful 40cfm Scythe Slipstream fan in the lower side cover, blowing in. The MB temps usually stay well under 40C (36C at the moment). It makes no difference in 3DMark, with my video card whether it's in the top 16x slot, or the bottom 8x one, so I've left it in the lower slot. I understand the need to try and keep the pipelines as short as possible, but that crams about 80% of all the heat generated into about a 1/2 Sq foot area. In my top PCIE slot, the back of the video card is slap up against the NB heatsink. It's no wonder the NB is such a bitch to keep cool!

I agree there is a lack of information in the article and I personally would love to see ambient temps in reviews as it seems everyone forgets that X cooler in 55F ambient does a crap job at 85F. By performance loss I meant that having an absurdly high flow rate doesn't have a negative impact on cooling, it just has little to no effect (again ignoring the heat dump from the pump).

I have not seen or heard of any 1w pumps, but if it's good I'd love to get one Most pumps only have a small heat dump but some of the higher performance ones are in the 20-30w range iirc.

 

Red_Maw,
Looks like I get to be the Guinea Pig! LOL!! I just ordered the CoolIt EOC for my computer. Considering the results I get at 3.8GHz with the Freezer 64, and knowing that the case airflow is excellent, I'll be disappointed if it doesn't work far better than the Freezer 64, especially when the heat of summer get's here. July and August temps are 110-115F, and I've seen 117F, so it get's very hot for a couple of months out of the year. I may even be able to use the 16x PCIE slot again! LOL!!

Stay Tuned,
Russ

 

russ that looks like a nice cooler.let me know how it works out. i might have to get me one.

 

redice,
I'll be posting the results, for sure!

Russ

 

Good luck, hope it works for you.

 

Red_Maw,
Thanks! The only bad review I read was from some place called Clunk, in the UK. Judging by their review, I would say they either didn't have the pump mounted correctly to the CPU, left the plastic cover on, or it had a defective base plate. The vast majority were positive reviews.

There was also another place where their forum said it wasn't a fair test between the EOC and the H-50, saying that both should have had the air blowing out! LOL!! The H-50 was designed to exhaust into the case, so how could it be unfair when both units were installed correctly, according to the installation instructions? I'll have better answers, next week.

Thanks again for the GL,
Russ
