C2D E6400 Running hot after install

[Dolorous Dave]

C2D @ stock with an Arctic Freezer 7 HSF on a DS3 is idling at 42c-45c about an hour after I built the PC. At full load in Orthos each core is hitting between 55c-58c. Is this normal? I'm totally freaked out about what's going to happen when I start to overclock this puppy.

Should I turn off the SMARTFan control in the BIOS? Should I give the Arctic Silver 5 some time to settle in?

Did some searches and either I'm an idiot or well...I'm probably just an idiot.

 

[Dolorous Dave]

Should I try a BB-sized dot of Arctic Silver in the middle instead of a line? It's running at 63-64C under full load at 3GHz.

bump for solutions

They are a little higher than normal I guess, but nothig too drastic. The AS5 should still be settling in yes and it will drop a few C's. Is your ambient temp high?

Hrmmm, never heard of a line of as. I always spread a even coat over the whole cpu. When doing p4 cpu I would spread even across the cpu then a bb size in middle, but the p4 chips were known to be concave!

 

[Dolorous Dave]

According to the directions on www.arcticsilver.com, the new C2D work better with a thin line right over the core.

I only do what works best for me!

Are you positive the heatsink/fan is secure on all four fasteners?

I replaced my stock hsf with a coolermaster hypertx, and I went from the 70's under load to the low 40's. But I'm convinced I didn't have a good connection. I don't think there's any way the cooler could make that kind of difference.

I'm not exactly sure what you are doing, but the first time I tried following the instructions from Arctic Silver my computer shut down due to overheating. I didn't know better at the time and just put the line on turned the heatsink on it a little like the instructions said.

I found you actually have to spread the stuff as thin as possible all over the CPU heatspreader. I use an expired credit card to do it since I don't have any razors, but it seems to get the job done pretty well. I was able to get my e6300 running about 34 idle with a cheap mass cool heatsink probably the equivalent of a stock HS.

You might want to invest in some of Arctic's other products for cleaning of thermal paste Arctic Remover and Purifier since those seemed to help as well.

 

[Dolorous Dave]

I've read in numerous places NOT to spread it over the whole heatsink on a C2D...

 

[TedKord]

I have the same problem, only worse. Using the stock intel HS and AS5, I idle at 50c according to CoreTemp. Under Orthos, I ramp up to about about 62-64c. Over time, my idles increase to upwards of 70c - that's when I break out the can-o-air and blow out the dust. (This is all at stock speed. At 2.3GHz, it's just 1-2C higher.)

I installed a Thermaltake HR-01-775 with a 120mm fan, and temps didn't decrease by much. I just can't get this thing down to the temps I see others hitting.

BTW, this is with three 80mm intake fans (2-front, 1-side) and a 120mm exhaust, and the power supply has both an 80mm intake and 80mm exhaust. Case flow shouldn't be a problem.

Oh, I removed the HR-01-775 because a) I couldn't fit my side fan in the case with it and b) with it in place, I had to remove the chipset fans, and the chips got too hot and became unstable even at stock.

(You can see my rig in the link below if that'll help with ideas)

ive hd similar problems with a ninja.

the core2 has been notoriously prone to shipping with a poorly implemented IHS or its own little heatsink - many have been concave etc, this is terrible for heatsink contact.

the solution is lapping, which voids your warranty btw.

but i got myself a lapping kit for my heatsink and chip and ill be doing that this weekend, i expect my temps to drop a very large amount.

ive also read from a lot of places spreading as5 is the worst way to apply it. a small amount is what is needed, as5 is designed to spread out where it is needed - and not much is needed at all. the line thing is the way as5 recommends you apply for the core2. a small rice sized amount in the middle is best for older processors

You want to be freaked out? My E6600 runs within a few degrees of the case temp, right around 47C, when idle. When under normal loads that keep both cores stressed, I'd peak around 57C. I'm just running Prime95, two instances, set to max heat/power consumption. The CPU shot right to 67C in about 15 seconds. Now it's at 68C, after the case has started to warm up, but the case is only 48C right now. Room temp is about 25C.


Looks like I'll be seeking out a new CPU heatsink. That's just crazy.
I guess first I'll pop the heatsink off this weekend and give it a tasty treat of Arctic Silver 5 instead of the thermal stuff that came with the retail heatsink.

Side question though - will using other thermal compound void my retail warranty?

 

[NotQuiteAPCGuru]

I'm using liquid cooling with AS5. Applied a very small amount and spread it over heatsink. I'm hitting 47C under 100% load. This can't possibly be right. I don't even want to think of what it would be like overclocked.

Would you recommend removing the processor, removing all the thermal compound and reapplying it/reseating it? I'm just really leary about taking this thing apart repeatedly.

 

[blanketyblank]

you are definitely using too much AS5 or something. You don't want a lot of the stuff, but I do find spreading it all over works the best for me. I think they warn you not to spread it too much so that it doesn't get anywhere else on the motherboard since the stuff is conductive. However a very thin coat works awesome for me, I spread it about to the point where it's shiny and you can read the print on the cpu.
As I said their instructions didn't work well for me, but spreading did.

 

[TedKord]

Well, I can't believe it, but a simple thing like removing the filter on the case side fan dropped my idle temps from 52C to 46C. And the filter was clean! I didn't realize it restricted the airflow so much. Still too hot, though.

 

[Alone]

Most filters restrict airflow. Sounds like you need more case fans to move the air around.

 

[TedKord]

I don't know...I have two 80mm intake fans in front, and one on the side.

For exhaust, I have a 120mm case fan blowing out, and the power supply has an 80mm pulling air in from the case, and an 80mm blowing it out the back. Actually, without cutting another blow hole somewhere, I have no place left to put anymore fans.

i'm having simmilar problems, i'm running water and my 4300 @3ghz 1.4V (in bios, 1.31 under load) is running 31 idle, 57 load. yet when i feel the air coming out of the radiator, it feels like room temp air

is this normal?

bwahahahaha... i see now why people thought i was bragging about my last temps.

i had the same problem. Anything over 1.4V and the chip seriously gets hot. At 1.45V i was idling at 27-29 which seems about the same as you. And i was loading at 51C.

Well one of my pumps wasnt powered on however. So i think your temps are within the range of your loop. Can i have more info on your loop parts? i might be able to help you stablize it a little bit lower if your on water. However it might take a bit of work for you to relap, and reloop your setup, if your parts arent in correctly.

Also after my inital panic and reserach, i found out, from XS forums.

Bs are the best, the only problem they heat up more <--- i have a B stepping. I guess thats why she was cooking a bit hotter then the others in my comparison.

 

[dannybin1742]

i can do better than that, i can take a picture of my setup, you might be impressed (i fabricated everything myself and built it at my office at the lab i work in.) send me a pm with your email address, i have no way to host pictures

 

[tehtank]

Man, reading after reading these forums a bit, I should really check my hs and such. My E6600 idles at 53c with stock cooling, haha.

Yes you do have a way to host

wow. And I thought my temps were hot... (I am not bragging. I'm just pointing out my own ignorance. Someone said my temps were high on a different forum).
I'm running my E6400@ 3.52GHz 1.52v and I'm idling at 32-35C (38-42 core temps) idle (18C ambient) and under Orthos Load, around 50-56C (52-58 Core temps). Intel TAT core temps max around 60-62C (CPU temp stays around 52C).
I'm using an Antec 900 with an air tunnel across the top of the case using 3 120mm fans and then a dual fan config on my Ultra 120 and i'm also using AS5 (i spread it around using a card too).
I think I have a total of 7 120mm fans in my case and the Antec 200mm Big Boy so I've got good airflow.

damn, i thought i had a lot of fans (6)


but my fans do equal to about 380cfm
