Conroe users, don't worry about high temperatures

edit 09/16/2006 - picked up the ThermalTake Sonic Tower. Nice passive heatpipe cooler. But the all mighty Conroe is just too much for it. With it completely passive, at full load, temperatures slowly, but surely raised to the same temps as my earlier no thermal paste test. It took like 10 minutes to rise to the throttle temp of 85C. Too bad, it's a nice looking heatsink. At least the rest of my purchase I'm still keeping - $50 Plextor SATA burner and $10 160GB SATA HD 🙂

I removed the stock HSF from my E6400 to apply AS5. Cleaned off the thermal pad and decided to run it without any paste between the CPU IHS and HSF. Full load temps reached 85C as reported by Core Temp and 83 as reported by Intel Thermal Analysis Tool and 65C from SpeedFan. The CPU ran fine without any problems at that temperature. So stop worrying about high idle temps. Conroe can run just as hot as Prescott. Why Intel listed a max temp in the low 60s, who knows.

And now with AS5 applied, load temps are 69C. Need to see if the temp drops after the breakin period for AS5. And note, my stock thermal pad temps at full load was 72C and idled at 39C before. And if I used the throttle option in Intel TAT, idle temps dropped to 33C. Ambient temp is 25C.

edit - screenshot

Yeah, the CPU throttled back because of the high temps. And why would the HSF be hot? There's nothing between the IHS and HSF to transfer the heat?????? I'm tempted to run it without the HSF installed 🙂

another edit - removed the HSF and the copper core was not hot at all. The IHS, was warm to touch though.
 
Wow, that's hot! :shocked:

I'm assembling my Conroe rig tomorrow when my motherboard shows up. I don't like the looks of those 3 stripes of factory thermal material on the stock heatsink so I will clean that stuff off and use Artic Silver with the stock Intel heatsink/fan.

How do you mean?
 
I wouldn't go there if I were you. I did 2 tests in the past few days on my system. While I can run 3200 @ 1.275 Vcore, it takes 1.35 Vcore to run 3400. Both of these speeds are Orthos and Memtest 12 hour tested. I'm in the process of testing 3400's Vcore at 1.325. 3200 load is around 56C while 3400 goes as high as 62C with my current HSF. I really don't feel comfortable running the CPU at these temperatures. I think will will cause problems down the line. Hope my Thermalright Ultra-120 comes this week.
 
Don't get me wrong, I'm not advocating to run your CPU at such high temperatures. I only left it running for like 10 minutes at that temp. But I'm sick of seeing all the posts complaining about running Conroe with idle temps in the 40s and at load in the high 50s and 60s. Your CPU will not explode in flames if running at that temp. So just a PSA to shut up about temps and enjoy your brand spanking new CPU.
 
Seriously, there is something wack with the temps on the C2Ds.

So many run so ridiculously hot...& here i thought newer 65 nm process = cooler.

It's not just only one mobo either...it's all over.

Really messed.

And yes, my temps are also insanely high...
I'll be reseating my HSF & applying AS5 when i get more time this weekend.

Why, you don't believe that software reporting of temperatures is often terrible?
 
If you touch your heatsink and its cold or warm, then your CPU isn't 85c......... the motherboards are over reporting by like 20c. Either that, or sometimes you have really bad contact.
 
Ok first of all. If the CPU gets too hot, it'll throttle. It's kinda hard to burn your CPU these days.

And yes, mobo sensors are horrible, use coretemp or something like it.

And lastly, conroe isn't even hot! I'm running a scythe ninja with stock fans, and the P180 with both fans on low. I'm getting 40s ambient and the room's like 25. This is nothing compared to the P4s 0.o

Hey, here's an idea!!! Why don't you flat out just call the OP a liar, LOL. 😀

Did you happen to check if your CPU was throttling at that point and kept you below 85C?
It's very possible.

No 65nm process means it uses less power, well should, the temp will not be neccessarily be lower, there are more transistors packed in less space, so even though there is less total heat there is prolly more heat per unit area. So u need a more efficient heat transfer to cool the chip.

The design/layout of the chip also plays a huge ammount at what temp the chip is running
 
How is that your chip runs at 60C and my 6400 at 2.13 with stock HSF runs at 27C idle. This was reported by my motherboard BIOS, is this reliable?
 
My E6600 is running at 25C idle... you might want to rethink whether or not having them that high is okay. I've also heard some reports of faulty temperature readings off certain C2D motherboards, so that could be a major factor.

If you touch your sink and it is not really hot, chances are that your CPU is at 85C or even higher. 😉

Reason: The IHS does not make proper contact, and the the heat is not absorbed by the sink.
 
I'm going to assume they mean no more than 61.4C? Or its designed to run at 61.4 regardless? I know it sounds like a silly question but someone has to ask. Might as well be me. ::chuckle:: Unlike the OP I would worry about high temps. Of course trying to figure out what the high limit is is what alot of people are asking.
 
I've got a Big Typhoon and a 6600 @ 3.2 (1.45v) and the max I see is 62ish C, and that's only when it's warm in this room, and running two instances of Prime95 or Super PI.

Though, the fan on the Typhoon is pretty quiet. I bet I could get much lower temps if I stuck a higher CFM fan on there. However, I've been stable for the week I've had this up and running, so I'm not worried about the temps at all.
