Finished the build - temps as expected?

Monkeyspaz5000 · 18 Aug 2012 at 23:38

Just finished my prodigy water cooled build.

Temps I'm getting are as follows....

I5 2500K @ 4.6 .... 1.37V
60deg Load

GTX670
45deg Load

240rad 60mm thick - fans running at 900rpm
120rad 60mm thick - fans running at 700rpm

Temps seem ok/as expected?

I should be able to run the CPU at lower voltage but I can't get it to drop for the life of me. Probably my inexperience here as my current clock is set by simply adjusting the multiplier.

Temps look spot on for a 240+120 setup.

Agree with PGI, against my air cooled 2500k and 670, especially as it's extra hot atm as well

Toothy1911 · 19 Aug 2012 at 08:56

Yep, looks about right buddy

Monkeyspaz5000 · 19 Aug 2012 at 09:05

Cool cool.

I like this watercooling malarkey!

temps seem good.. do you know your ambient temp in the room at all? i had an ambient temp of 36 in my room last night :/

Monkeyspaz5000 · 19 Aug 2012 at 10:00

No idea mate, but it was really hot last night!!

You planning to overclock your GTX 670?

Monkeyspaz5000 · 19 Aug 2012 at 12:22

It is mate. Pushed it as far as I can.

1240mhz boost and can't remember about the memory.

The 670's run really really cool, especially under water, you'll also notice you probably won't need to increase the power limit at all to overclock as the cold VRM's don't need to draw so much power - note this does not give you extra OC headroom, voltage becomes a limit way before power consumption.

When I had my 670 WF @ 1365/7550 on air I would hit around 86% peak power under synthetic stress, that dropped to about 70% peak power with water

Just for reference (to show you're temps are in check) the 2600K (4.8ghz 1.32v) + 670 (above OC) loop I had with a single 1080 rad gave synthetic stress temps of ~55c on the CPU and 40c on the 670, so three times the rad space only dropped temps over 4-5c

Monkeyspaz5000 · 19 Aug 2012 at 13:07

Cool. Good to know.

Yeah, it would be good to have voltage control on these cards!!!

pgi947 · 19 Aug 2012 at 13:10

iirc there is a bios thats supposed to allow 1.21v, but seems very hit and miss as to OC results however. Its a shame Nvidia felt the need to cripple the voltage on these cards so much, I truly believe the 670 I had would have managed near 1500mhz on the core with some voltage control.

My ambient was 39c! Then i remembered i've got an old aircon unit in the shed.
Nice and cool now =)

pgi947 · 19 Aug 2012 at 13:15

If that was me that air con unit would be strapped to the side of my case

Think this but with a PC case

It is a pitty especially for people with cards under water.

Not sure how much mine would take though as its reference design pcb.

Very nice, how much did it cost you to build this water cooling computer? I'd love to go into water cooling but one day maybe, i'd overclock the hell out of CPU's just to boil my cupa' in the morning.

Monkeyspaz5000 · 19 Aug 2012 at 13:40

Not 100% sure on cost.

I'll price it all up later. I know it cost me roughly £400?? That's for the watercooling side.

I'd hate to think what the complete cost was!!

DeanV255 · 19 Aug 2012 at 13:47

Wow about £400 on watercooling? I must have missed the memo on how expensive they were. I'm spending £410 on a 2700K, motherboard and a Noctua NH-D14 to almost finish of my computer (Just RAM to go), thats possibly just baby food to you haha. Great system though will keep you happy for a long time

unless you have cat like me who would find away to burst the water pipes even if i put it in a safe within a safe within a safe.

Toothy1911 · 19 Aug 2012 at 13:52

Yeah mine was around £400 too. For just all the water blocks, rads, tubing, pump, res, fans etc.

pgi947 · 19 Aug 2012 at 14:21

£400 is probably about average for a decent CPU + GPU loop. You could easily spend upwards of £1000 on a multi block/rad setup.

Think I'm around £700 so far, but I have purchased GPU blocks for 4 different cards.
