E8400 temperature ... Again!

[imported_qwester]

I have my E8400 installed on an Asus P5E-VM HDMI board in a Microfly case. Using the stock HSF, and the case has a 80mm intake and a 120mm exhaust (+PSU exhaust). I applied AS5 instead of the paste that was on the HSF. All settings in the Bios are on default (no OC).

Temps under idle:
Asus AI Suite: 51C
Core Temp: Core 0: 55C - Core 1: 49C
Real Temp: Core 0: 45C - Core 1: 39C
Voltage in CPUZ: 1.112V

Highest temps I saw running Orthos for 10 minutes:
Asus AI Suite: 69C
Core Temp: Core 0: 70C - Core 1: 67C
Real Temp: Core 0: 60C - Core 1: 58C
Voltage in CPUZ: 1.144V

Room temp when test was done: 25-26C

I was checking different threads on the forum and noticed that there are a lot of people with lower temps than mine, even with an OC!
I am not 110% sure I installed the HSF correctly because this is the first time I install a HSF of the type that the C2D uses ... although I made sure that the white pins went thru the board and seemed to be latched on when I looked on the back of the board. Other peoples' reported temperatures made me a bit concerned that I might have screwed up the install.

Do my temperatures look normal? Should I try to remove and reinstall the HSF?
Are my higher temperatures due to this being a uATX case?

Thanx for the help

While I can't comment on temps with the stock HSF, I want to point out that most other users are also using aftermarket heatsinks and fans that are superior to the stock HSF. That could potentially account for some of the disparity, although I don't know how much of a difference it really is. Someone else can probably fill in that blank for you.

Also, what program and version are you using to take your temp readings?
Edit:
Nevermind, I'm blind, you were using an Asus utility to measure the temps. I'm not sure how accurate that thing is. E8400's have a different TjMax (supposedly) than previous CPUs so you may want to grab either the newest CoreTemp or RealTemp and check with that.

I am using the Asus utility AND CoreTemp and RealTemp, all the latest versions. I just added spaces in the middle of the names ... oops .

Ya I was thinking of getting a better HSF, but thought I'd give the stock one a shot, plus make sure of dimensions and what the Microfly case would fit ... there isn't much clearance above where the CPU sits, because of a support bar

Any ideas on a low profile HSF that will be able to lower my temps?

 

[DarkRogue]

Sorry I am terribly blind in the morning.

It seems you're using the old (or non-revised) CoreTemp, since CoreTemp's values are consistently 10C higher than RealTemp's. CoreTemp used a TjMax of 105C, RealTemp uses the more accurate 95C value.

So, 40-45C idle and 60C load..
Doesn't sound too bad but hopefully someone else can tell you if that's good or bad for the stock HSF.

 

[imported_qwester]

CoreTemp version 0.98.1, with 105C TjMax ... that's why I included both CoreTemp and RealTemp

 

[Donts00tmesanta]

i would try reseating the HSF

also make sure to use something like arctic silver

I'm running a Xeon E3110 (essentially the same cpu), default everything, stock cooling, in a fairly well ventilated Antec P182 case. My idle temps varied between 37 and 40 C, and I maxed at 59 C (Real Temp) running Orthos a few hours. So either that's what the stumpy Intel cooler gets you, or perhaps my heatsink isn't seated properly either (I don't rule out the latter possibility because I never feel I get those bloody pushpins right).

I too always wonder if my temps are too high, but as DarkRogue observes, almost everyone posting on these forums is an overclocker and uses aftermarket cooling. And something like a Tuniq Tower or Scythe Ninja is clearly not comparable to Intel's stock heatsink. I'd like to see more figures from plain vanilla users -- if there are any others out there...

My ambient room temp was probably slightly over 20 C.

 

[imported_qwester]

Just tried reseating it. I used a little bit less AS5 this time, I probably put a wee bit too much last time.
Result: the same

I guess I'll have to shop for a new HSF.

Any ideas on a good HSF that is:
1- No wider than the stock intel HSF. It's already almost touching my northbridge cooler.
2- No more than 1 inch higher than intel stock HSF ... support bar crosses over the CPU location.

Scythe has a new sff heat sink that seems pretty trick, it's called the Mini Ninja. Not sure if it will fit but I love my Ninja...and I've been a Thermalright owner for years.

Newegg also sells these sinks.

at 115mm tall it wont fit. My clearance is about 80mm or slightly less

It's a bit hard searching for a short HSF, not really a spec that is advertised

 

[DarkRogue]

If you're not overclocking I wouldn't worry too much over it. The stock HSF isn't absolute crap or anything. Even if it was, those temps look fine to me, 60C load is a bit higher than most around here would like, but it's certainly not life threatening to your CPU either, it's just the limit of the stock HSF.

FWIW, I have a E3110 also and have idles around 30C with load arouns 47C...these numbers derived from RealTemp w/ a Scythe Ninja HSF......I ran at 3.2GHz @ 1.07V...

I have basically the same problem. Not overclocking my month old E8400 yet, but decided to take a look at temps in CoreTemp (ver. 0981) and HWMonitor. They are showing 44C idle and 58C under load (both cores).

But I am using an Arctic Cooling Freezer 7 Pro (using the thermal greese they supplied as I understand from many here, that it is as good as Arctic Silver 5) not the stock HSF. I have a Gigabyte GA-P35-DS3L motherboard and a nice cool case (Antec P182).

Now I am wondering with temps this high to begin with what will happen when I start to overclock.

 

[imported_qwester]

If you use RealTemp to measure your temperatures they will be reported as 10C lower. As I understand RealTemp is more accurate for the E8400, because of the TjMax temp used 95C vs 105C in CoreTemp.

So you'd be at 34C under idle conditions and 48C under load conditions, which I guess is good for the E8400. I'm idling at 45C (core0) 39C (core1) according to RealTemp with the stock cooler. I guess my sensors might be a bit less trustworthy, because the 2 cores are constantly off by 3 to 7 degrees with core 1 always lower than core 0, under any condition even after reseating the HSF.

 

[kschaffner]

I have a e3110 and I'm idling at 33c core 0 and 33c core 1. Running at 4.0ghz at 1.3vcore and its under a Tuniq Tower with AS5.

 

[Caminetto]

Thanks for the RealTemp info.

I have to wonder if there are different "batches" of the E8400 out there that account for the disparity between those who are claiming 29C or lower at idle, and us.

As I said, I used the Freezer 7 Pro (which is a pretty fair HSF) and has the thermal paste pre-applied. And depending on who you talk to, that paste has mx-1 or mx-2, and is superior to AS5.

Too bad there is not a definitive source on what temps one should expect with this processor with stock and after market coolers.

 

[Winterpool]

If we want to get an idea of the 'proper' ranges of the Wolfdales, there are a lot of variables we need to control for. I think, ideally, as a baseline, we should provide temperatures idle and under load at default (3.0 GHz) clockspeed and voltage under stock Intel cooling. We'd also need to know all relevant components and especially the ambient room temperature, the case cooling, and perhaps the case ambient temperature (or at least the 'system' temperature). Also, of course, what tools we're using to measure (Real Temp, BIOS, laser thermometer, etc).

Many people assemble their systems immediately using aftermarket cooling, so we'll never know their stock figures, heh.

Realistically, the best one can do is trawl these and other forums for figures under condition X, etc.

For those trying to compare results under one cooling solution to another, Frosty Tech measures cooling solutions based on final difference from ambient under certain power dissipation (usually 150 W and 85 W). For example, the Tuniq Tower 120 supposedly cools about 17 degrees better than the Intel stock cooler at 85 W.

I do wish, at minimum, that punters would list their cooling solutions when they offer their cpu temps. I too get alarmed when others report 30 C idle temps when I'm lucky to get 37 in a cool room. Not to mention the 10-degree difference between Real and Core Temp. I don't believe I've seen temps that far below 40 C idle or 60 C load with these cpus and stock cooling. If your measurements differ substantially, please report them. I've precious little faith in the job I did driving in those pushpin mounts.

I just tried undervolting my E8400. I set the CPU voltage at the lowest setting that the P5E-VM's bios allows (1.100v).
Under load CPU-Z is reporting 1.024v (1.064v idle). The good part, under load RealTemp: core0=56C core1=50C, a drop of 4-8C from my previous test, and I believe the ambient temp is higher now than when I tested a couple days ago (the heater is on).

Since it is stable I see no reason to set the voltage at auto. I am gonna leave it undervolted!
