My idle temps. ok?

[Synomenon]

I have an Intel i7-3770T (45W TDP). I do not know how hot this thing is supposed to run. I'm using a Corsair H60 with it. Idle temps. right now are:

Core 1: 29C
Core 2: 33C
Core 3: 29C
Core 4: 34C


Do these idle temps. look normal or should they be lower?

 

[ShintaiDK]

Perfectly normal.

 

[Ed1]

It depends on the ambient temp (room temp) but those temps are about what my 3570k at idle (mine runs 27-35c depending on core) at 72 room temp . So your in the ballpark .

 

[Synomenon]

Ok, so put together another system. Used the i7-3770T again. This time though, I used a low-profile heatsink:

Thermaltake Slim X3
http://www.thermaltakeusa.com/products-model.aspx?id=C_00001602

I replaced the heatsink's 80mm fan with a 92mm Noctua fan and the fan is sucking air away from the heatsink / blowing air upwards towards the PSU (the system is in a SilverStone SG05).


I'm running SpeedFan, Core Temp and AIDA64. The system has been idling for an hour now and these are the temps. showing in each program:
AIDA64
CPU: 53C
Core1: 43C
Core2: TRIAL
Core3: 43C
Core4: TRIAL

SpeedFan
CPU: 54C
Core 0: 44C
Core 1: 45C
Core 2: 44C
Core 3: 45C

Core Temp
Core 0: 43C
Core 1: 44C
Core 2: 43C
Core 3: 44C


Considering I went from a Corsair H60 to this low-profile air cooler, are my temps. still ok? Core Temp says this under the CPU info., "Tj. Max: 94C".



Also, SpeedFan shows a fire icon next to the CPU's temp. (54C) and one next to "HD1" which I'm not sure if it's my Intel 240GB Cherryville or 240GB Mushkin mSATA SSD. The temp. listed for HD1 is 128C. I touched the mSATA drive and it's just warm. So is the Intel SSD.

The motherboard is an ASRock Z77E-ITX.

Temps are fine if it doesnt throttle (Tjmax). Just use Coretemp or Realtemp.

 

[Synomenon]

What do you mean that it's fine if it doesn't throttle? What does it mean if the CPU throttles?

I did post temps. from Core Temp in my post above.

The core temps are fine idle.

But idle temps are also meaningless as such. What are your load temps?

Intel guarantees it can run at tjmax throughout its estimated lifespan.

Ok, I ran the preset Small FFTs test in Prime95 and ran Core Temp. to make sure the cores were at 100% load.

After around 20 minutes of testing, all four cores were hovering around 82C.

Should I let it run longer? Are these temps. way too high?

Perfectly fine temps.

Perfectly safe and normal temps, keep in mind Ivy Bridge chips are almost as bad as fermi.

The fire icons means nothing, except that you haven't adjusted the desired temps in Speedfan (which by default are a bit too aggresive). The 128C on the hdd means nothing either, just that the temp sensor isn't recognized.

Perfectly safe and normal temps, keep in mind Ivy Bridge chips are almost as bad as fermi.

Those temps are indeed perfectly safe and normal, certainly in a sff case. But Ivy is nothing like Fermi, it's only when you overclock to high freq that temps skyrocket, while Fermi temps skyrocket by default.

So, I've been running the Small FFTs test in Prime95 for over seven hours now and the highest temperature any of the cores reached is 83C.

Core Temp shows this currently (Prime95 still running):
Core 0: 75C (Max 81C)
Core 1: 75C (Max 81C)
Core 2: 79C (Max 83C)
Core 3: 74C (Max 80C)

Ambient temp. in this room is ~24C.


So, everyone think these temps. are ok? Or should I try to find a better low-profile heatsink?

 

[Vectronic]

They're fine, pretty much no real-world application will get your CPU as hot as SmallFFT will.

Are they great?...no, they could be better, but they're fine.

 

[Synomenon]

Thanks for the reassurance everyone.

 

[Ed1]

As others have noted that is fine ,especially for that low profile type cooler .

If you installed a mid range tower cooler like hyper 212 your temps be lower in prime , in mid 60's c area , that is if case has good flow .

So I was looking at other heatsinks and found the Silverstone NT06 Pro. made by Silverstone.
http://www.silverstonetek.com/product.php?pid=368

Looks like a perfect fit for the SG05 which is the case this build is in:
http://www.silverstonetek.com/product.php?pid=210

Silverstone says a low voltage CPU like mine can be cooled passively with the NT06 Pro..

Anyone think the NT06 Pro. can cool my CPU passively in my case? It looks like a much better heatsink than the Thermaltake Slim X3 currently on my CPU.

Here's a simple diagram of the airflow in the case:

The front 120mm fan is a Silverstone Air Penetrator:
http://www.silverstonetek.com/product.php?pid=257&area=


The fan cools the motherboard and components in the case. The SFX PSU has an 80mm fan which is sitting above the CPU, drawing hot air in and out the back of the case. The heatsink fan on the Slim X3 is 92mm and is blowing air up at the 80mm PSU fan instead of down onto the CPU. I did it that way so the PSU and heatsink fans don't fight for air.

While no first hand experience with Silverstone , that HS fan combo looks real good for that type small form factor case . not sure on heatpipe diameter differences but the silverstone looks to be optimum for that case

 

[Synomenon]

Nvm.

 

[Synomenon]

So anyone think the NT06 Pro. will be able to cool my CPU passively while still giving me better temps. than the current Thermaltake Slim X3?

 

[Synomenon]

Ok, found a build log of a similar system:
http://www.overclock.net/t/1338999/build-log-air-travel-sg06/0_100

If I use the NT06-Pro. on my board AND put a 120mm fan on the NT06-Pro. will such a large fan on the NT06-Pro. starve the PSU's fan of air if I have the 120mm fan on the NT06-Pro. blowing down onto the CPU / motherboard?


Here's the diagram again of the current airflow in the case (using the Thermaltake Slim X3 heatsink w/ 92mm fan):

The top of the NT06-Pro. would be right up against the underside of the PSU / its 80mm fan. The 120mm fan mounts to the underside of the NT06-Pro.'s fins.

Just the opposite , if the PS is exhausting out of case and your HS fan pushes up to two will help evacuate the case .
For sure you don't want then working against each other (HS fan blowing down) .

I would run a fan with HS, though you might be able to get away with just PS fan passing enough air as it is so close to the HS .

I would try it with and without fan on HS if you rather not have fan . Just test it good under load to make sure temps are not bad, it is small case , they tend to run hotter .

Edit: I should read slower, you don't want HS fan blowing down in this case, that would be bad IMO .

 

[Synomenon]

So if I put a fan on the NT06-Pro. in this case, the fan should be blowing up into the PSU, right?

 

[Ed1]

So if I put a fan on the NT06-Pro. in this case, the fan should be blowing up into the PSU, right?

Yes, and remember to the intake fan and vents on side will help, even though the fan is pointing up your MB will still get airflow past it as the air has to get into the intake side of fan . It maybe not as much airflow over MB as fan down but with that case your not going to get good results that way .

Well you could try it but don't think out come would be good . I would go fan blowing up .

 

[Synomenon]

Ok, so I replaced the Thermaltake Slim X3 last night with a SilverStone NT06-Pro.. I installed the NT06-Pro. without a fan. I decided to try it "fanless" since I want a quiet system.

I've been running Prime95 Small FFT for 3 hours and this is what Core Temp is reporting:
Tj. Max: 94C
Power: 44.7 watts
Core 0: 59C (Max 67C)
Core 1: 60C (Max 67C)
Core 2: 64C (Max 70C)
Core 3: 60C (Max 66 C)


So, I'm running a fanless heatsink now and also have lower temps.. Also, not sure why Core 2 has always had higher temps. with every heatsink I've tried.

What does everyone think about the new load temps.?

 

[ShintaiDK]

Core 2 got higher temperature due to its physical location. Its normal behaviour.
