E4300 Temps Discussion

Ok, here's the issue. When I first got my E4300, I OC'ed it to 2.88 GHz and I noticed that it was getting 80 C on load using Orthos with a Scythe Ninja heatsink. This seemed unusually high so I did some forum browsing and found lots of conflicting information. The E4300 has a Tjunction of 100 C compared to the E6000 series chips which is 85 C. Some people also believe that certain temp monitoring programs, such as Core Temp, are reporting the Tjunction temp wrong. I recently switched over to water cooling and the load temp went down to 70 C. This lead me to conclude the following:

I noticed that many people are reporting their E6600's running at 50 C. This is 35 degrees below the Tjunction. Likewise, 70 C is 30 degrees below Tjunction for the E4300. This would mean that nothing is wrong with the chip, it just runs hotter by design. There seems to be a misconception that ALL C2D chips should not exceed 85 degrees and should operate at most 60 C on load.

I wanted to ask what you guys thought of this. Is 70-80 C on load for the E4300 too hot, or well within specifications? Either way I've had no trouble with the chip, it was stable on 2.88 GHz at 80 C when I ran Prime95 overnight and it's also stable on water cooling on 3.2 GHz at 70 C.
 
That chip is running hotter then most E4300's.
My chip tops out in the 50's at 3.3Ghz, 1.48v, on air cooling.
 
10C to tjunction @ 3.15GHz @ 1.45V and stock cooling. A little high, but I never reach these temps during normal usage.
 
If your dual core is running hotter than a quad with the same overclock...then there is something wrong.

IMO...anything over 65C at load is too hot.

That would make it 90 C on full load?

It might be running hot but there's really nothing else I can do. I checked the thermal paste, it's pretty much spread as optimally as anyone can get it. Water cooling system is also the most expensive kit Petra's Tech Shop sells. Just tried playing some games, temps cap at about 65 degrees and hovers around 60.
 
No, 75'C.

>.> Mine's 54'C in the 2.7-3.0GHz range full load. 1.3375v. That means you're using a TRU120?

It does seem high for watecooling, to repeat myself see my post above concerning if it is running within specifications. However it never hurts to run as cool as you can. You failed to mention what your Vcore is and have you tested to find the lowest Vcore that is stable at your OC target ? What specific cpu water block/system. I am not impressed with a lot of cpu block hold down methods and wonder if that could be some of the issue. However that is a pretty damn good OC on that chip and you probally just did not happen to get a really good die. You cant kill it with heat, it will just shutdown cool off and be good to go. Too high of a voltage can damage it beyond repair.

What is your room temperature?

Here are a few suggestions:

1.) Open the side of your case and see if that helps, if it does, then you have poor case circulation.

2.) Push down on the HSF or waterblock, if it helps, then you are still not making good contact with the IHS.

3.) Check how flat the IHS is. I had a 7C idle/10C load drop from lapping my IHS and HSF.
 
I also had a problem with my E4300 getting a bit warm. At 3GHz with 1.35 volts, my E4300 would run hotter than my E6750 at 3.6GHz with 1.49 volts. Not sure of the temps off the top of my head, but I think my E4300 was almost 70C and my E6750 may have been under 60C.
 
I've got a 4300 that runs pretty hot also - can't remember the temp exactly but it is in the high-60s/low-70s I think. I finally figured, what the hell. It runs fine, is super stable, and the voltage is comfortably low - who cares if it gets hot. If Intel sets the throttling temp at 100C then what difference does it make if my chip is running 60C or 70C, it's still 30C away from what Intel considers to be an unsafe temp.

Bottom line, if it's stable, don't worry about it.
 
I got it up to 3.42 GHz stable on 1.4 V. The ambient temperature in my room is something like 92 degrees in the afternoon and around 80 at night. Taking off the side panel wouldn't help since it's water cooling and my radiator is mounted on the outside of my case. The water block is a D-Tech Fuzion.

It amazes me how many people completely miss this point about allowable temps specified by the CPU manufacturer. I mean, people are more than happy to push their CPU past its RATED speed, yet shy away from temps that are still 30C UNDER RATED maximum.

What engineering basis do people have that say "more than 65C is too hot IMO", other than its a good number to pick that your current megacooler can keep your CPU temp below? I reckon they are just plucks that have become fokelore over time.
