Radiator / Fan Change

[axer]

SR1 360(3 x apache 120mm(Push) + 2 x 200mm(Pull )

How did you fit this in, there isn't enough room between the top of the motherboard and the top of the case to fit an SR-1 and a set of fans in push?

Also, won't you get an imbalance due to having two different types of fans in a push/pull config?

How could we make better cpu blocks then?

They already have a pretty thin base don't they... Copper has a fairly good thermal conductivity approximately 600 times that of water. Presumably the limiting step for raising the temperature of the water is then the rate at which you can transfer the heat into the bulk of the water.

With a higher restriction block (say with a one piece copper heatsink in it to massively increase the surface area, or even multiple little pipes) improve the rate of the heat transfer sufficiently?

Essentially to improve things we need to look at how to heat up the water more efficiently from the cpu

Well you can go phase, tec or chiller, but you could also think of some way to increase the turbulence of the water as it hits the block. Say having an injector before the block so you get like a shower head effect as the water hits the base of the block. This should help but you would massively increase the pressure around the cpu block and a fair pressure drop after the cpu block.

I'm not sure it's a problem though tbh. Most of us worry about a cpu hitting 70 under prime or IBT, intel cpu's are good to about 90 degrees, so even under high stress situation we have a fair bit of head room to go. We just don't feel comfortable doing it.

Do you have any photos of your setup?? This is very relevant to my interests

got home from work last night to find my rig switched on & frozen on the bios screen, initially I thought I had cooked my cpu, but after running out this morning grabbing a 2700k & actually testing with another motherboard its looking like my maximus extreme z maybe deceased.

Both cpus show as bad according to the LED's but work fine in my P8P67. I have partially broken down the setup performing an autopsy once I have rebuilt will take some proper piccies(not using my phone).

There is just enough room not much wiggle room tightest bit is the 8 pin power connector in the top corner.

Very possibly a slight imbalance but the 200 mm pull fans are spinning at 700 rpm (90-110cfm )& the top of the case has small vents either side of where the radiator hangs underneath which are over lapped by the 200mms so I doubt there is much of an issue with pressure, the apaches shouldn't be impacted.
after I have modded the case bottom I plan on dumping the apaches again and swapping the cm 200mms out for some shiny bitfenix ones

Actually looking fwd to trying this 2700k under water so far on air seems to use slightly less vcore 1.33 than my 2600k(1.375) @4.8ghz.

I thought I had done a bad mount with this heatsink, load temps @76oC IBT but I guess I have got use to water temps as idling @21oC

I've now finished messing around/changing things and things are now setup like this:

Xigmatek Elysium Full Tower case with Hardware Labs Black Ice® SR Series 420mm Triple Radiator in top (very tight squeeze!) and 3x Apache 140mm fans configured in 'push'.

I also have a Hardware Labs Black Ice® SR Series 120mm Single Radiator with 2x GT 1450's in push/pull where the rear exhaust fan would go (I had bought a 140mm rad but I couldn't get the case on!

Unfortunately I've had to remove the 200mm side panel fan to accomodate the rear radiator and have placed a 140mm Apache in its place.

With the CPU now clocked to 4.8Ghz @ 1.34v my idle temps on the CPU are ~32-36degC and GFX are ~35-39degC.

After a session of BF3, max temps are usually around 50-52degC for CPU and 45-55degC for GFX.

Under Prime95 I seem to top out at 60degC on CPU and under IBT ~65degC.

On the whole I'm pretty pleased, whilst I did not manage to get the system @ 5Ghz stable with sub 70degC temps as per my target, I'm much happier with how quiet the GFX card is under load vs the stock cooler :O
