aLL i can say is that I would not let a machine run at over 75C no matter what.Quote:

So you are getting 68c real with all 8 cores at 100% and only after weeks 24/7 @ 100%??? :shocked:Quote:

Naw the room is around 65-70F. I dunno what the deal is. My case is open and the metal of the case is cool to the touch. The only thing even slightly warm is a single 3870 (after benchmarking) and the ram and the NB, but not even hot, just a bit warm.
Sounds like the heatsinks do not make proper contact with the cpu's.Quote:

Yeah the fans hit full rpm at I think 55c set in the bios. So basically anytime I push em past 50% load. Soon as I stop the benchmark they quickly, quickly go back down to idle temps, so I know the heatsinks are making contact.Quote:

It's ok I guess, I have a new tube of AS 5 and some isopropyl alcohol handy so I guess it's worth a shot. Y'all think I should run it for a day, let it cool for a day, then prime95 to let the paste burn/cool or just go for it?
The fans dropping in speed fast doesnt mean the heatsinks are making proper contact.
It is an indicator that the IHS is not touching the cpu cores or the heatsink properly.
This is because heatsinks do not cool down immediately when the system becomes idle. They take a few minutes to reach near ambient temperatures.
dump the stock thermal pads, try some IC7 if available or AS5 if not and after seating pull the HS off and see that it is spread out properly.Quote:

I learned the hard way on this by using a set of coolermasters designed for socket 604 and socket 771 although the same bolt(holddown) pattern has the cpu sitting just a tad lower.
I saw 92C at bootup and learned REAL fast..:D
The fans don't drop in speed really fast, the temps drop really fast. Once the temps are below the full speed setting in my Z7S bios they turn off from full speed, maybe a few minutes like you said. This I'm sure you know is controlled by my bios settings. I could set it to 70c if I wanted. Default is 55c.Quote:

Thank you all for your responses but I'm still not willing to concede my HS's are not touching my CPU's correctly. That in itself is laughable after a week of benchmarks, etc. Like I said they are cool to the touch @ 100% load and nothing shuts off or down. Stock Cooling FTW. :clap:
EDIT: I want to add something. There is stock cooling with a fan and heatsink, and stock cooling with only a heatsink. I am not using passive cooling but active cooling and these things don't mind the heat I throw at em with a fan. I happen to ALSO have 2 servers using the passive HS only cooling (dual XEON 5410's) IN 2U's and they are doing very well, and have been since March. Thanks for everyones time and comments.
Try this, go into bios and set so that fans run at 100% always and see what happens.. I think your right, but not 100% sure..Quote:

Here's a 5340 that had poor core-ihs contact: http://www.mediafire.com/imageview.p...j1wdra&thumb=6
I have 9 fans in this rig, much more than my 2U racks. The stock non passive cooling in this rig cools the cpus from 100% to idle temps in less than 2 minutes, so I know they work. :yepp:Quote:

Anyways your warranty doesn't cover after market coolers now does it? Nuff said I think.
Hey, I don't care what you use as long as it's working.Quote:

Thats how we all learn,spreading the info back and forth.
We were just concerned that your HS weren't making proper contact.
I appreciate your input. It could be a lot of things. The fact remains however that the cpus are CONSTANT temps at idle after a week and only jump under load. That means I have good contact, but correct me if I am wrong. I'm using stock Intel thermal pads after all - but they haven't failed me ever before. Like I said these CPU's don't even need a fan and thats fact because I have 4 in 2U's running fine for months without fans over the heatsinks. They are the exact same CPU's and you can check for yourself.Quote:

I chose stock cooling, but of course I haven't upped these 2.3's to 5Ghz either. LOL.Quote:

My systems I need to do work for me, and if they work under load, I'm a happy customer.
Stock cooling FTW, again. :shocked:
I have 2 5340'sQuote:

No two CPU's are the same.
EDIT - Then there's my E4300 that goes 100+...
The heatsink (s) should feel warm to the touch at full load.
In my system, the heatsink is around 38°C (measured with digital thermometer) when the cpu is at full load (around 57°C)
It's not possible it feels cold when you're seeing 90°C in my opinion.
These 2 boot at 30 or 40c - I'm not worried anymore after talking to Intel. Stock cooling, nothing super fancy like modifying a heatsink fin and crap like that. I also have a p4 that runs 80c normal, it's been fine for over a year. Cheers. Mine run hot and don't crash, nothing to complain about here. :rofl: Hey I had these to 127c actually. :up:Quote:

I am not willing to debate this since I'm the one judging the results. Anyways, I don't even need a fan on my cpus and I can refer you to plenty of documentation to support that.Quote:

Do you run stock clocks on those 5410's? The lower the clock, the higher the stable temp threshold.. mine crash at 3,2Ghz when they hit 80C real/90C Everest.. I tried without fan just to see, lol ;)
Oh and in my rig, everything gets rather hot.. NB, Rams, even the Heatpipes from the HR-01's. But temps are ok even at 30C ambient, plus this system is a rock at FSB 430 :up:
I would say cold heatsinks are a bad thing. I'm sorry but I just cringe whenever I hear "I get X(high temp imo) and the heatsink isn't even warm!" If I see high temps anywhere, I expect the heatsink to burn. Of course, it could always just be the temp probes on your CPU are fubared.
Sounds like he wants our help but only if it's what he wants to hear lol.
Extreme temps and cold heatsinks = something isn't right.
Never seen a stock heatsink that was worth very much.
Still running stock but I will try 400 FSB this weekend at some point.Quote:

As you can see the passive heatsink is rather larger. Al models from the 5405 to the 5450 come with the option of active or passive, so I think it's a rather well proven point that you don't need to go active cooling. Either way like I said before I'm not trying to cook these by overclocking too much which would in my opinion require better cooling. However, since the heatsink and fan for each model from 5405 - 5450 is identical from Intel, I think I'm set up to 3Ghz.
Part of the reason my heatsink for the cpus aren't warm to the touch is because of the fan directly above them, and the room they are in. Also I'm not feeling them from the top but rather the thick base/bottom (one piece unlike your HR's), and the side fins. There is a 10d temp swing from my upstairs and downstairs, and currently the rig is on a table, in the case with both sides open, a top exhaust fan, front input fan, dual rear exhaust fans so it's getting a lot of airflow downstairs where the cold air shoots out from the ceiling.
Once I get my huge Sigma SD-10 batts recharged I'll take some professional pics for ya all. ;)
With my Q6600 G0 at 3 GHZ when running WCG on the stock cooler, the heatsink is hot to the touch. The CPU more or less stays below 70C, so I'm fine with it.Quote:

If the cooling wasn't working, they simply wouldn't boot or hold an idle temp, nor would they drop quickly from load. That's just the facts. :welcome:Quote:
