Case temp 77F and I idle at a solid 86F

coretemp shows the cores range from 82-86 besides 3 which runs cooler around 77.

For Haswell having a thick TIM under the plate I am seeing only a 2-3 difference which means thermally it's very effective at heat transfer.

This is using the stock cooler, fan at 100% using AC5.

Warmest temp not including burn in programs is around 125F [Skyrim].

I'd say not too shabby really.
 
It is more relatable if you report your temps in Celsius.
Those look like good Fahrenheit temps to me.
 
i get around 80c at load, 30 to 40c at idle. i7-4770, and by at load i mean with all 8 cores active. it's quiet except for when compiling :/ and then fan seems to take about a minute to spin up real fast. but as long as you can not use too much cpu all the time it's not too bad.
 
i5-4430 with stock cooler in a slimline case with a single 80mm fan for exhaust. Temps are reported by HWMonitor

Idle:
Ambient: 22c
CPU: 30c
Case: 28c

While Running Prime95:
Ambient: 22c
CPU: 61c
Case:53c
 
Ugh metric :p

cpu 30C
case 26C

Cores 25-29C

52C [skyrim]

Prime 95 is a different story though, I can easily hit threshold of 212F [100C] and throttle down.

Lian-Li mid tower with twin 140's up front, 120 in back and on top.
 
wow how do you guys get so low? my haswell runs hotter than my ivy bridge, and both of them are running way hotter. although ambient is probably about 26c?
 
64c at load and 33-36c at idle. Doing 1.2v and got the CPU clocked at 4.25GHz.

I run a Corsair H80i Cooler. Don't they call that a "Closed Water Loop"?

About 32c Idle with speedstep/C1E and adaptive voltage. 75c at load with Intel burn test at 4.6GHz 1.3v with Swiftech H220.
 
Im at 28c but its pretty warm inside 75f, load temp is harder because it depends on the version of prime 95 and if your running small fft etc.
 
22-24°C Idle
54-56°C Load
20°C Ambient

4770k at 4.4Ghz, 1.205v manual voltage in a custom loop, 540mm rad, no delidded CPU.
 
Watercooled. 4770K

CPU OC'd to 4.3, VCore 1.1375 (I think)

idle 26-28C ( loop includes two 290Xs)
loaded 48-50C ( GPUs show 47C at load):D
 
What kernel cpu governor are we measuring temps against?

I'm sure idling at 3.5ghz, temps are higher than 800mhz.

From my experience it doesn't matter at what frequency the CPU is idleing or at what voltages as long theres no load the temperatures are pretty much the same especially with a Haswell CPU.
 
What I find odd is least going by easytune is regardless of what the cores are at going by coretemp the processor is very slow to actually heat up.

I can RAR a long file and the cores will get to 135F and be stable yet my CPU [maybe easytune is not accurate] it goes from 86F up to maybe 90F, strange.

So a 50F+ gain in core temp yet only a 4F gain on the CPU sensor.

Thats because maybe easytune its measuring the socket temperature in the mobo not any of the DTS inside the CPU package or core dies.. Cores will always be hotter than the CPU package, specially measuring the Tcase temp the 4770K has a max Tcase of 73C.. While the Tjunction its max 105C. Tcase its the temperature inside the CPU Heatsink and most mobo show this temperature and not the temperature of the cores. Nothing odd really.. If you open for example aida64 you will find there 3 temperatures for CPU.. "CPU" "CPU package" and "CPU cores 1,2,3 and 4" you can see both 4 cores at 100C and the Tcase still be at 60C and all its OK.

Those are REALLY good temperatures for your setup.
I lost 30c delidding and resorting to direct die cooling with liquid metal tim but my load temperatures are only slightly better than yours running newest best prime with small fft.

Then again mine took more than 1.205v (1.275v) to be able to pass that test for 24 hours too. But a Haswell at 56c under full load even with water is unheard of for me until now.
 
i7 4770 (non-K on stock cooler)

It idles anywhere from 38-42c, depending on ambient temp and stuff (machine is right next to a window). I've seen it as low as 30c on a cool day.

This is under kernel 3.12 which doesn't use pstates, not that that has anything to do with temps...

Thanks :) I was thinking about delidding my CPU but kinda afraid I mess up and i'm very happy with the build at the moment. The temperatures are with the GPU being idle and just stressing the CPU. If I leave a GPU Bench like Unigine Heaven running at the same time the CPU goes up to 62-65°C but not higher. GPU stays under 40°C at all times.

My loop in detail:

Laing D5 Pump (Aquacomputer USB/Aquabus version), at 75% which results in 3800rpm
Aquacomputer Cuplex Kryos HF CPU Block, TIM is CLU
Aquacomputer Kryographics GPU Block, TIM is PK-3
XSPC Dual 5.25 Reservoir (black one, not acrylic)
Alphacool Nexxxos XT45 540mm Radiator
Tubing is 13/10mm

Its installed in a Silverstone FT-02 and I use the AP-181 Fans in pull configuration. Both pump and fan speeds are controlled through an Aquacomputer Aquaero 5 LT controller its very nice.

Just curious, why are computer temps generally reported in Celsius? I personally use Fahrenheit because I can easily compare that with my room temperature

Well because most of the world isn't called America ? Jokes aside, most EU and Asian countries use Celsius I think.

Off topic aside, my temp average about 29C (Google for Fahrenheit equivalent) when idle for 15 minutes.

Forgot: ambient 22C and no OC
Edit: mis-typed, 39/32 instead of 29/22

Turned up the top fan on my Lian-Li and I am now seeing pretty low temps at idle.

19C CPU
23C System

coretemp says my cores are between 77-79F except 3 which is a chilly 70F.

Certainly work for me and the AC5 should be long cured by now [6 months].

for the same reason why computer components and specs usually refer to mm over in. The metric system :p

I mean I already understand that, but this being a primarily North American forum, and most of us likely use Fahrenheit, wouldn't it make more sense to compare relatively in Fahrenheit so we would get a better relative feel of what the temperature is?
 
I'm American, I monitor hardware temps in Celcius. This thread makes perfect sense to me.
Fahrenheit would confuse me.

as an american, I use celsius for measuring computers because that is what everyone else used, if someone tells me their fahrenheit temp I have no idea how warm it really is.

OTOH if someone says "its 20C outside" I also haven't the slightest clue, F for AFK and C for computers :p
 
I recently built a mini-ITX Z87 system with a 4471 i7. Obviously I'm running everything in stock (CPU multi is locked) yet the temps are discouraging.

Granted, its a small case (CM Elite 130) and the cooler is slightly better than stock (CM Geminii M4 low profile), but.. still. I get around 82 degrees under full load with latest linpack.

Idle temps are very low however, around room temperature (25 degrees).

Is Intel still using crappy thermal paste in the Haswells?
Click to expand...

oh yeah and i think they will keep using that method instead of soldering.. anyway.. i think its good to use thermal paste so people can still delid and get much better temps than soldering methods.. =) once one delid a chip replace the TIM or even better use direct die contact to cooler never will want to back..
 
I was not too thrilled with the max temps either. Idle with C1E and speedstep, yeah I can idle at around 27C with a case temp of 23C.
Intel burn or P95 I can easily go over 100C but my thought is that is not real world temps.
In fact with 84 watt TDP max I seen the burn test pulling 90 and that is just not going to happen in the real world.
More realistic is playing a game or trying to do a few things at once, even then I only managed 57C which is quite reasonable.

My core2duo E6750 idles lower, around 21C without C1E and speedstep with stock cooler though.

Adaptive voltage causes that huge temp jump. Being stock clocks you should set manual voltage of around 1.05~1.1v.

Here's some work I did back in august when I bought a 4670k and working to lower my temps (copied from my post at oc.net).
Bios vcore: Auto (stock 1.13 and kicks up to 1.25v during stress test)

Hyper 212 Evo + Included CM paste = 94c
Hyper 212 Evo + AC MX-2 paste = 88c
Hyper 212 Evo Lapped (1k grit) + AC MX-2 paste = 84c



Just started under-volting and testing 1.075v Manual Vcore. Currently running P95 Small FFT for 20mins as of writing.

Hyper 212 Evo Lapped + AC MX-2 paste = 68c

Edit: IBT 10-pass SL:Very High = 71c

Regardless, when gaming I usually sit around mid 50's. I only do single-player games though.

I think temps are measured in C as cpus are also rated in C. Also: When measuring things in experiments ("science") metric is generally used as well.
