Hot temps at Idle

[XxKINGxX40]

Hey guys I just finished re-doing my water loop. I added a new radiator.

 

Before:

Res -> Pump -> 240mm (60mm thick) radiator -> 2 GPUs -> 360mm (30mm thick) radiator -> CPU -> Res

 

Now:

Res -> Pump -> 2 GPUs -> 140mm (45mm thick) radiator -> CPU -> 360mm (30mm) radiator -> 240mm (60mm) radiator -> Res

 

I did a simple overclock on my i7 4770K to 4.2GHz @ 1.155V. It's rock solid stable at 1.155V. The idle temps of the CPU is at around 42°C and GPUs at around 33-35°C.

 

At stock clock and auto voltage, the idle temps are at around 30-35°C and GPUs at around 25-30°C. 

 

The load temps are both the same. Max CPU temp at 100% load is around 70-75°C some times it will get as high as 80° but not much after that.

 

Did I just get a terrible CPU or is there something wrong I did?

 

My PC's Specs:

 

Case: Phanteks Enthoo Pro

Mobo: Asus Maximus VI Formula

CPU: Intel i7 4770K

RAM: Corsair Vengeance 1600Mhz 16GB (2x8GB)

GPU: 2x Geforce GTX 770

PSU: Corsair RM850

Storage: 2x Samsung 840 Pro 256GB

Pump: Alphacool VPP665 D5

Radiators: 240mm (60mm thick), 140mm (45mm thick), 360mm (30mm thick)

Nope, that's pretty much standard. You increased factors that directly influence the production of heat from a CPU.

 

In any case, idle temps matter very little, unless it's crazy high. This is within normal range. 

 

 

Edit: If you actually meant 1.55v to get it to 4.2Ghz, you have lost the silicon lottery, terribly.

What are you using to stress the CPU?

Sorry for the late reply. No, I mean 1.155V.

Intel Burn Test or Prime95

Those aren't bad temps from my perspective. In another thread I was told aida64 is the way to go and I am trying to find my point of equilibrium, where the temperature doesn't rise anymore. I've found with these extensive loops at load the temperatures start great but over a duration they climb until the system gets to a point where it is a sustained temperature. I don't think a lot of people do this. For example my temperature at start of a load test on the CPU was 67-70 but after 20 minutes it's now 80-83c and still slowly climbing. I haven't adjusted anything yet, fan speeds, pump speed. I recommend aida64. It's much better than prime and i've used that for probably 10 years. Mine is stock by the way.

 

I have a dual GPU on a single card and a 4790k with a 120mm 60mm rad and a 280 60mm rad with 4 140mm fans, one exhaust, and 2 120mm fans.

 

Currently it seems my plateau is 70c on the GPU and 86c on the CPU.

 

[XxKINGxX40]

So you guys think those temps are OK at idle? I'd love for them to be at around 30°C at idle for both the CPU and GPU

I think they're totally reasonable. I'd be more curious what your load temps are over an hour long stress test.

On Intel Burn Test on Maximum 20 runs, the max temp was 81°C

If I could get 81c with a 700MHz OC I would be pretty happy especially at that voltage. I'm curious why you think there's something wrong?

@XxKINGxX40

 

to me it sounds like a big air bubble that won't shake out. stock voltage is usually about

1.2v and you have lowered the voltage to lower than stock. nothing changed, other than

adding the 140x 45 radiator, tubing and location. you should be idling about stock temps

(6°-8° above ambient). as you increase from stock voltage then the temperatures begin

to increase.

 

picture of the routing or device placement could help.

[XxKINGxX40]

I got some air bubbles out and the temperature went down by around 5°C. Now the idle temp is at around 35-40°

How does it look under load now?

On 100% load with Prime95 or IBT, around 77-80°

I have the exact temperature profile as you do. Maybe it's high, I don't know, I'd like it to be cooler but I don't want loud. If I fire up the 3 main rad fans to high from medium I drop 10c @load, to 67-70. I also have the 60mm thick rad. 2 of them actually, (280mm top and a 120mm front). I found more CFM through that main one resulted in much reduced temps. Noctua 140mm x2 fans in push and 1 in pull underneath for the top 280mm rad.

 

What is your air through the radiators like?

[XxKINGxX40]

I have Corsair SP120 x 2 fans on my 240mm 60mm thick rad on push. On my top radiator, I have 3 SP 120s in pull. And on the rear, I have a Noctua 140mm in pull on my 140mm rear radiator.

 

I have 2 extra SP120 fans that I can use on the 60mm radiator, but I just need the screws. Alphacool only includes 1 set of 30mm screws.

Yeah I never understood why they don't supply all sets. Should have included 2 lengths I thought? You can just cut the others to be shorter.

Really? How do I cut the others?

 

And I know right? It makes a lot more sense to include enough screws for push/pull then push or pull and another set for a radiator shroud.

[airdeano]

because push/pull on the low FPI radiator does minimal in temperature drop of

CPU/GPU. depending on rpm, between 3-8° maybe. push/pull would be for a

2600rpm loud fan set going to p/p could keep effective cooling with lower rpm

(1100-1400rpm)

Just get a pair of long handled snips or wire cutters and line em up, make a nice quick 90 degree cut. I found push pull helped quite a bit with the thicker radiator and lower CFM, low noise, fans.
