How's these temps?

[Tullphan]

I've got an MSI P35 Neo2-FR w/an E6300 @ 3.2gHz...idle 42c (core0) & 37c (core1), load 52c (core0) & 48c (core1).
I've got good airflow, I think...housed in a P182 using Slipstreams (Kaze-Jyuni 1200rpm) in the upper hdd cage, rear & top.
Previously, I was using AS Ceramique w/the Tuniq Tower's fan blowing towards the rear of the case. I read that the proper configuration was to have it blowing up.
I took the HS/F off, applied some IC7 according to manufacturer's specs, positioned it according to the manufacturer's specs & lapped it (E6300 is lapped as well). I honestly couldn't tell that much of a difference after going through all that.
Now i'm tempted to position the Tuniq back the way I had it (blowing towards the rear exhaust) to see if that makes a difference.
Do the temps shown above seem good/average/poor considering my setup?
Thanks in advance.

Those are good temps, especially to be using such low RPM fans. And you'll want to keep your Tuniq blowing upward.

I'm just curious as to why it should blow upward.

I agree w/ Myocardia....If you want better you need a 1800-2000rpm 120mm fan....I would recommend the blowing out to the rear also....I have tested this a while back with similar Scythe Ninjas and Infinitis....

I cannot figure it out, unless they just figure heat rises???? Perhaps they know most Power supplies have intake fans underneath, and it is a way to push the air to that point. Which is exactly why most people blow to their rear exhasut fan....It basically helps to establish one directional way for air....With the intake blowing from the front towards the fan on the heatsink that pulls and then pushes the air towards the exhaust fan which pulls then expels the air out the back....Multi directional air flows create turbulence and dead spots where air will be trapped that an eddy in a river...

With my 182, I dunno if I actually need two exhausts, do I?
So their recommendation to mount it w/the fan blowing upwards has nothing to do with the arrangement of the heatpipes?

Good point....However the thermalright has similar design and I believe so did my scythes and they showed installing it the facing the rear exhaust fan....I think current of air flow trumps the need to have heatpipe orientation in this case...

I am not sure the direction of the heatpipes will make much of a difference since in theory the side placement of standard towers would not be optimal to begin with.

 

[Tullphan]

So you think it might help to turn it around so the fan will blow towards the rear?
I'm really pondering that Xigmatek HDT-S1283, but i'm not 100% sure it'll fit in my 182.
I've noticed a few bent fins (top 3 or 4) on my Tuniq & I think that the Xigmatek if 4-5mm taller.

 

[Duvie]

I would...maybe a tad faster fan would help...

I ran my E6600 at 3.26ghz with a Scythe Ninja B and an antec tri-cool fan and I loaded at 48-50c with 24-7 running of 2 instances of Folding at Home...

Was your load temps with prime95? if so....that isn't bad at all...

The real thing to look at is the swing from idle to load....in reality is most of the heatsink from 20 dollar cooler to 60 dollar coolers if compared with similar fan size will all be close to one another in idle temps...It is under load where we find the pretenders...

I think in reality in an AC controlled room you have an ambient temp of 22-23c...INside case will be a few degrees higher...Now 26-27c is more likely...that is the best in my opinion the Tcase temp could ever be. Now remeber the temps you see are at the core...I dont think even if you threw a bunch more money at it you will ever get better then 32-34c at idle. the best cooler will only minimize that swing once loaded to keep it in the high 40's to low 50's.

 

[Duvie]

Just remember that prime95 will generate more heat and stress then you likely will run into in your daily uses for your PC....If you can stay with what you listed above...I wouldn't spend anymore money on it....

 

[Tullphan]

Those temps @ load (52c core0 & 48c core1) were taken w/2 instances of Prime95 running. Idle, there were 42c (core0) & 37c (core1). The room temp was ~20-21c. I'm not sure of the case temp. My 7900GT w/Zalman 700cu was 38c idle...it'll get about 10c warmer @ load.
I think I may be able to get a little more out of it...still running stock vcore...just don't know how high to let those temps go.

 

[Tullphan]

Well, I thought that before I took my system apart to re-position the HSF, i'd swap out the stock Tuniq fan.
I had a Cooler Master Y720DCD-25T1-GP 120mm Blue LED Silent Fan lying around so I put it in there.
So far at idle i've noticed a 5c drop in temps. I'll load up Prime95 before I go to bed & see what the temps climb to.

Those temps look fine. Prime95 is a decent test but will not get that highest core temperatures. Try superprime to see how high it goes.

nobody runs prime as an application around here anyways...It is already more extreme then any real world activity he will do...

What is the point of heating it to a point that is unrealistic?

prime95 is fine...dont waste your time...you would have still been fine at 62c

Well yes in real world use but my point is Prime95 is not the holy grail of CPU absolute max temperature. There are programs that will get the cpu heated to levels that can induce throttling or system malfunction with default cooling and quite possibly at default speeds - for example. The Intel Thermal Analysis Tool was designed for this function so that manufacturers of mobile devices could determine if their cooling provisions were adequate in the upper area of operating extremes. The idea is if the system can pass such a test it should survive everyday use - say if the heat sink fins get clogged with dust or the room becomes very warm, etc.

Many folks here use distributed computing which in fact will stress the cpu parts continuously and if that's the objective it's nice to see how the cooling system copes with something that can push it even further.

 

[Tullphan]

OK...here's a screenshot of my overclock.
I switched out the fan in the Tuniq from the stock to a Coolermaster Y720DCD-25T1-GP 120mm Blue LED Silent Fan as I said earlier & noticed an immediate difference in both temperature & noise.
While running Prime95, the temps never got above 51c.

Results

I didn't show a screenshot of the memory, but it's Corsair XMS2 running 911.8 MHz @ 4-4-4-12 (1:1). I think I have it @ 2.1V, IIRC.

Perhaps I can shoot for a little higher overclock?

Also, according to this, the VID Voltage Range is 0.85V - 1.5V, but the bios for my motherboard won't let me go below (I believe) 1.3V. Since it appears to be running stable at the (lowest) voltage I can set it at, it'd be nice if I could lower it a little more somehow.

Agreed....

However top temps of 24-7 F@H running all 4 of my cores is anywhere from 6-8c cooler then running 4 cores in prime95.....That 6-8c should be sufficient to cover me in running F@H which was an application I was actually running.

There was an app I used to use called SNM. I used to run it with dual cores...i am not sure if it handles 4 cores, but it usually would load the cpu another 5c+ over prime95. I used it to induce throttling as well.

I just want ppl to see that getting such extreme temps from stress testers is not somethinig you should hang your hat on soley.

So lets say he runs the new app and causes a crash. And lets say that app achieves temps 5-6c higher then prime95 which achieves 5-6c higher temps then an amp he may run. Let alone he may never run the app for 24+ hour periods. Does that mean he should lower his OC? I dont think so.....


the nice thing about prime95 is that it will test me for those warmer days, and when the cooling gets a little build up of dust on the fins and fans before a routine cleaning....

i think you are set...dont mess with it....

For the most part most of this similar tower design of heatpipes and tower of fins will cool relatively close to one another. the main difference in some of the testing can be the cfm of the 120mm fans they use....

A TRUE or Tuniq tower can be very sclose when ran with a similar 80-100cfm fan.....both will excel at cooling what you need

 

[nullpointerus]

LINPACK will do ~15C more than Prime95 on my chip.

Sadly, I had TM2 enabled, so the throttling kicked in ~90C and saved my chip.

 

[Tullphan]

It's funny...my temps were almost the same when lowering my FSB down to 400 from 456 so I cranked it back up...hehehe.
Duvie, I assume you lapped your TRUE because of what i've read of them being slightly convex?

Nope....

 

[Tullphan]

So is it possible to have two of the same model chips set up in the same configuration (motherboard, case, HSF, etc) & get different temps?
I've read where one chip may outperform another of the same model, but is it possible for chips of the same model to overclock the same but one have better temps (idle & load) than the other?

Of course its possible. No two semiconductor chips are identical, just like potato chips and snowflakes.

They are "binned" by similarities that matter to the manufacturer and to the consumer, but by no means are two chips ever going to be identical. There are millions of individual discrete transistors and circuits inside a chip, on average they all perform approximately the same but they will always be differences at some place after the decimal point.

 

[Tullphan]

Well, considering i'm getting temps ~3-4c difference w/3 different HSF's, i'm going to assume I have a chip that tends to run a tad warm.
