Why is my E8400 so hot??

[Ad1tya]

Hey,

Alright, Ill start off by saying, that Ive done 3 re-mounts, with different AS5 / MX-2 Applications, and all 3 have yielded me the same results. Almost the same anyways.

Im running a DTek Fuzion with the 4.5mm Nozzle (Earlier I was running the Quad Nozzle, as I was using my Quad).. Temp's have improved by 4C, just because of that.

Ambients : 24-25C

My Load temp's are ~63/63C ... Prime takes it upto 65/65.

Last night, when the Ambients were 21C, Temp's were 61/61C Prime Loaded.



Only thing I can think of is that either coretemp is wrong, or the VID coretemp shows is correct.

I tried testing 333x9 @ the lowest vCore I could (1.200 BIOS Set, 1.110v Loaded Prime), It was stable for 1 hour, then I shut it, since I wanted to OC :P). Temp's during that run, were like 55/55C Prime Load.

Im running rock solid stable, Prime completed 9 hours this morning @ 4.3Ghz @ 1.39vCore Load.

Oh, Contact is perfect as well...

What could be the problem?

My E8400 is at 42C-44C at idle under water (stock). Under load it's 52C. Not sure what to make of it at the moment.

[Dr.Leary]

Mine is also as hot as yours. ~40C idle and ~67C load @4300MHz 1,42v under water.

[Viss]

They are hot little chips. I have tried 3 of them, under Tuniq all idle around 40 and high 50 while running prime with only 1.325v in bios.

Those temps seem pretty typical of many of the water cooled E8400's, with many load temps in the 60's and 70's...which seem surprisingly high to me.

Cooling, or even voltage increases seems to have little effect on Wolfdale temp readings. Some guys have removed their cpu fans completely and temps go up only slightly. I get the same cpu/core temps with the cpu fan on 800rpm, 1600 or 2250rpm...or with the voltage at 1.2v or 1.6v, makes no difference according to CoreTemp & CPUID Hardware Monitor. Intel's TAT does not work with Wolfdales.

[Eastcoasthandle]

My E6850 was 31C idle and 44C-48C load at 3.6GHz. But that was using the P5W DH Deluxe which only has 4-pin 12V connnector (not sure if that's why).

[Ad1tya]

Hmm.. Well the E6850 isnt the same as a E84/85...

Im just surprised that the temp's are so high. I know Intel has said that the max. safe temp is 75C. But still, Id rather have it below 50C :P.

[Bail_w]

can someone remove their E8400's IHS?

[KiD0M4N]

can someone remove their E8400's IHS?

Thanks for volunteering.

awaiting result.

I'm experiencing temps around 65-70C on the Intel QX heatsink with my E8400 around 4400MHz, 1.5v. Haven't tested lower volts yet, just got the chip about 7 hours ago and I've been running benchies for a review. On the next heatsink in line(Scythe Ninja) I'm sure temps will drop 10 degrees to only be countered by raising the Mhz to 4500 or so. Got 4275MHz stable on the aluminum E8400 cooler, 4365 on the Q6600 heatsink, and now 4400 on the QX heatsink. Can't wait to put this chip under the cascade this weekend.

[s0lid]

Perhaps the heatspreader isn't enought straigth.
Lap it and tell the results.

[aoch88]

I wonder how on earth did all the reviews come out with the idea of E8400's giving lower temps. It's either the chip doing terribly hot or the software is not reporting correctly. I had my E8400 on IP35 PRO and Foxconn Mars but both shows high temps.

[clone38]

My E8500 reads the same temp at stock and with the cpu volt @ 1.5v with core temp so dont worry.

[haoster]

i have my e8400 running at 4230mhz at 1.368v vcore.
under water, apogee gt, idle at 42c and 68c under load...as5 used.
guess that is pretty high.
i think i didnt install them right.

[C0ncrete]

Just tested my old E6600 and my new E8500.

6600 reports idle of around 34 to 37 degs.

E8500 around 43 to 45 (bios however says 29)

[Pandamonia]

My E8400 Temps SUCK

i installed a TRUE to replace my Zalman 9500 and the temps are exactly the same! 38/42 idle 60-65 load at 1.34v

i dont understand it

[s0lid]

Temp sensors can't read temps right. Try everest instead of coretemp.

[xMrBunglex]

my E8400 idles around 30° and has not gone over 43° even for a second under full load in my warm house. maybe you guys should back off the volts a bit.

[Dr.Leary]

Temp sensors can't read temps right. Try everest instead of coretemp.

Everest, speedfan, coretemp and Dual core center all report about the same

[AriciU]

It's because o the volts mate. Anything above 1.33v and they heat up like crazy. I have around 66C load @ 1.48v on air only but my VID is higher then yours. At 1.6v i hit it up with some orthos and temps jump straight to 75-83C region.... so you can see how hot these things get when applying serious voltage to them, compared to the Conroes or even the Kentsfields.

Ooh, and by the way, the lower the VID the CPU has (vid shown in coretemp), the higher the temperatures you'll get when giving it some voltage and upping the mhz.

I put 2 fan on the TRUE
at 1.43v Idle 35C/37C _ Prime95 60C/58C

[Brian MP5T]

I agree that droping the volts to a near minimum but stable level should help but perhaps the CPU is just going to run hot like the old P4 3.0+ Ghz did...

[Eastcoasthandle]

has anyone tried remounting yet?

[stone_cold_Jimi]

Ooh, and by the way, the lower the VID the CPU has (vid shown in coretemp), the higher the temperatures you'll get when giving it some voltage and upping the mhz.

Like I've said elsewhere, think about it. 1.6 vcore minus 1.3 VID = 0.3v and 0.3/1.3 = 23% overvolt. But 1.6 vcore minus 1.0 VID = 0.6v and 0.6/1.0 = 60% overvolt. Imagine overvolting the whole mobo by 60%, you think it'll get hot? Or catch fire lol.

[Dr.Leary]

But they are just asking for more and more volts. I think I buy another new fan rather than lower the volts
