Resonable temps? Just installed a WC kit

Hi guys!

Just bought some second hand WC parts.

EK-Supreme HF Nickel/Acetal
EK-DCP 4.0 Pump
EK-CoolStream RAD XT (240)
EK-Multioption RES X2 - 250 Basic
2 x Schyte GT 1850 @ 1200rpm

OCCT logged about 58C max after a Linpac run. i5 760 @ 4.0, 1.32v

Resonable temps?
Ambient ~22C
 
38c over ambient is pretty darn good IMHO. Hows the fan noise with those Schyte GT's?
 
Ah ok, great then :)

Went from a Corsair H50 Push n Pull with 2x GT 1050. Temps dropped around 15-20C.

Well the 1850 GT's make some noise due to the airflow @ 1850. But a lower RPM they are very quiet. The motor is very stable and IMHO the best 120mm fan there is. The downside is that the motor itself is quite large and make up a larger deadspot in the middle compared to other 120mm fans.
 
Good stuff, thanks for the reply guys.

EDIT:

Follow up question. If I want to add a fullcover block to the 7970 I'm adding in a few weeks. Will an extra 120 rad be enough?

Techincally, even the dual radiator will be enough, but more cooling is better than too little... 360mm worth of radiator should be plenty. The EK radiator you have is one of the best.
 
I should be able to fit a 140mm rad in the front of my Fractal Arc midi. Would be nice to be able to keep the fans at low rpm even with a gpu in the loop.

I have checked the dimensions and a EK-CoolStream RAD XTC (140) should be able to fit without to much hassle. Even Push n Pull should be able to fit.

But if I mount a rad in the front the next concern is the airflow.

Top: 240 rad with 2xGT1850 push - exhaust.
Rear: 120mm Nexus - exhaust
Front: 140mm Fractal - intake

Should I reverse the airflow letting the rear fan push air into the case and exhaust air in the front?

Or push air into the case through the front rad and keep the airflow as it is?

The Fractal case has a sidepanel fan mount but when I added dampening mats I covered that opening (as well as all the other fan openings (bottom, top above 5.25"). That could be an option for intake, but there's no filter there and I guess the sound level would increase.

Ive always liked white tube, but I dont like the extra hassel of not being able to see how the system is bleeding on initial fill...
 
I have made some changes to my setup:

  • New case (Corsair 650D)
  • Fullcover for my Radeon 7970
  • Additional 200m rad
  • New res

Pump: EK DCP-4.0
Radiator (top): EK CoolStream XT 240mm (2x Scythe GT 120m 1850rpm)
Radiator (front): Phoboya Xtreme 200mm (BitFenix Spectre Pro 200mm)
EK AMD 7970 FullCover
EK Supreme HF

All the fans are controlled by the motherboard (silent fan profile)
(GT ~1400rpm, Spectre Pro ~ 700rpm max)
CPU gets about 60C in OCCT Linpac and the GPU about 45C in Furmark.

Resonable? :)

You should put a rad between your GPU and CPU. You'll get better temps.

Loop order don't matter, so long as res is before pump. The high heat capacity of water means that after passing through a block the coolant doesn't rise in temperature very much.
 
Indeed, it doesn't rise much, but it does infact rise. I'd be willing to put money that he'd loose 5c or more if her moved the top 240 to between the GPU and CPU.
 
Hmm, I'm not sure if I want the additional tubing. But a few degrees drop is something that wouldn't hurt. The GPU is already cool enough so I would easily trade a few degrees with the CPU...

I put the 200mm rad at the end of the loop to get as cool air if possible into the case. I'm not even sure if it makes a difference but that was the initial thought.

I HIGHLY doubt the difference would be 5C.

That guy had a CPU and 4 GPUs in his loop, and the difference between the warmest and coolest points in his loop was 0.6C. Water temp becomes surprisingly stable once the system has been running for 20-30 min.

Some googling on my side supports this. Seems like delta is less than 1C in most cases.

If that's the case I'm not gonna drain this baby again :D
 
Yep, loop order literally doesn't matter. The only thing that does matter is having your reservoir before your pump. Aside from that, go for aesthetics or minimum tubing.
 
I'm not quite satisfied with the temperatures I'm getting.

This is after a few hours of Battlefield 3 gameplay:

The motherboard and PCH seems to get a bit hot?

I'm tempted to reverse the airflow on the front fan and rear fan. Pushing cold air from the rear and pushing out the hot air through the front rad?

I think your radiator would benefit from having cool air cooling it.

Does the side of you case have case fans? If not a case fan on the side would help get more fresh air in the case.
 
Ok I finally have to ask. Do Intel processor just run hotter than AMD processors? I am running a 1075t Thuban at 3.9 at 1.4v and even folding 24/7 the temps never get above 33 cpu and 30 cores. I keep my house at 70 deg F. I have my cpu, northbridge and gpu all in the loop. But I know if I was reaching 55 to 60 deg C I personally would be doing something to change that. I don't like my cpu getting over 35 deg C and my gpu over 40 deg C.

AMD chips are not assigned crit temps to handle the higher heat ranges that most Intelsat can. OTOH AMD chips are built like tanks, and if they're run extensively overheat they'll still boot and work albeit with voltage leaks; whereas the Intel chips won't even POST.

30C idle is quite common for any chip. Also remember Thuban thermal readings were very bugged and often read 10C low. Depending on the over clock and the architecture 50-60C for an Intel isn't unreasonable.

No fans on the side, the 650D has a clear window on the side panel. But Corsair sells a mesh insert that replaces the window and makes it easy to mount a side fan(s).

One of the temp sensors on the Samsung HDD provides the airflow temperature. Which indicates that the air coming from the front rad i about 30-35C. I'm gonna try and reverse the rear fan as start.
 
Hehe it turns out that I had put one of the top fans as intake instead of exhaust. Explained the high temperatures.

This is more like it:

I suspected some type of air flow issue for your case.

I think adding a fan intake on the side or bottom would help to get some more cool air in the case to help that top radiator cool off a little more.
