My Temps are officially not good.

Jonni Nitro · 09-26-2009, 10:00 AM

After all that work I finally get my loop running and I am disappointed by my temps. In fact, there must be something wrong. I am not sure if I have just over loaded my loop or if I mount my block wrong. I followed the intructions and everything seems right.

I am idling around 38-40C with ambient of about 75-78F. Also, my gpus are idling at 3-4C lowering then my cpu. I am afraid to tighten down the cpu block more. When loaded temp jump up about 10-12C

My loop specs and order:
Res
655
2xMCR320s stacked with S Flex 75CFM fans and spacers
HeatKiller 3.0 LT
MCW30
MCW60
MCW60
Res

I know there is a lot in this loop, but i really didnt think my temps were going to be this bad. Is it really just too much heat for these rads?

Your CPU temps just to 52C at its highest on load and thats not good to you?

There's only so much you can get from a 3x120mm with 4 blocks on the loop including two GPU's known to be hot. Your temps are quite fine.

millertime359 · 09-26-2009, 10:26 AM

What are you using to get load temps? I don't see anything wrong with your temps either, especially with ambient hitting near 80.

malkiewicz · 09-26-2009, 10:38 AM

Yeah... the 6600 can handle higher temps easily (I would consider it a workhorse)... For some reason your build should have lower temps because my ambient temps hit 80+ and I was able to keep it well under 55C with 1 360 radiator...

Jonni Nitro · 09-26-2009, 10:41 AM

I used Intel Burn Test. I know that Prime95 is better, but I am just doing testing right now. I was really thinking my temps are horrible, but maybe not. What can I use to load the gfx cards? I ran 3DMark Vantage and my gfx cards never went over 45C.

millertime359 · 09-26-2009, 10:53 AM

I thought F@H puts some stress on the GPU.

Your temps are plenty fine then. I wouldn't worry about it.

This (these?).

Your temps seem fine and what you state seems perfectly normal. The only thing that jumps out at me are the stacked rads with that fan combo. Stacked rads really need strong fans to be effective and those are quite weak. If you really want to improve temps I would start there and give us a breakdown of how many you are using.

You can't cross compare temps like that. There are too many variables to call a comparison of setups accurate.

EDIT: For GPU temps try Furmark or OCCT GPU test.

malkiewicz · 09-26-2009, 11:01 AM

faster3200... Your right.... Sorry... If I'm going to compare I need to be more specific / detailed.... I was just trying indicate that his temps are okay but it's possible to get lower temps ...

Hehe, when the fan failed on my 6600, the temp rose to around 140 degrees for about 5 minutes (with a nice burning smell). I attached a new fan and it's still going strong :P

Do you honestly think your gpu's and cpu should idle at the same temp?

do you know how water works?

The coolant temp is considered your floor. We call that ground Zero.

From ground zero, the only way your other blocks can read ground zero, is when there OFF.

When there on, its like you lighting a little match. How bright the fire is, depends on how much power your component draws.

So no there is aboslutely nothing wrong with the specs you gave us.
Your just trying to compare your temps with someone else on the forum who probably has a lower ambient then you do.

Or has a much more expensive system then you do.

malkiewicz · 09-26-2009, 11:16 AM

Yeah... I cooked one of my Q6600's & 8800's before when my pump failed... The liquid in my CPU block actually started to boil.... I sold it to my friend last year and it's still running strong.... That's why I run dual pumps now...

Did you use a backplate for the CPU block? If not, the bending of the mobo may lead to poor contact.

*sigh*

there is no poor contact.

first off his ambient is around 25-28C check..
So if i use math i can assume his coolant levels are roughly around 30-35C. Now lets Check by assumption and see if his deltas are alright...

So his CPU is idling 38-40C... which means he has a delta of 8 as his low. That sounds okey...

Now his GPU is idling at 34-35 which has a delta of 4 low...
That sounds okey again...

Why? cuz his gpu is drawing less power then his cpu is, and therefore his cpu is hotter.

So whats wrong with his system again?

Oh his only problem is he didnt pay enough and split his loops up with more radiators or he didnt put his rads in front of an AC.
But i dont think that would fit in his budget or objective.

Spawn-Inc · 09-26-2009, 01:15 PM

either un stack those rads, or get 9 fans going for better temps and performance.

Zigosity · 09-26-2009, 01:36 PM

Those temps look fine to me. O_o. My rig at 3.6 right now is getting like 64-65 under load and idles at ~40-43... Not to mention you've piled a whole bunch of stuff into one loop, which is going to give you less than ideal performance.

Jonni Nitro · 09-26-2009, 01:59 PM

Thanks for the comments guys. I will agree that these fans are probably to weak and I could have either split the loop or add a 3rd rad before the gpus. Next time I break downt he loop I am going to change my fans for sure and probably add another set. I was trying not to overload my fan controller, but then I ended up with one channel free. I might consider a push/pull with a shroud in between next time.

I am using a backplate, btw.

My rads. The bottom fans are the actual fans. Top ones are gutted for shrouds. I should have cut the bottom of the case and got taller feet for better intake. Live and learn.

millertime359 · 09-26-2009, 02:25 PM

You can always go and get some sticks of wood and use them to jack the case up. It won't be pretty, but will get you by till you get the time to tear down again.

Dont take it personally...

i tend to sigh a lot.

There isnt anything wrong with his system.
And im trying to save the op from tinkering with it b4 he does break something.

we wont really know if that will fix his wants either, without a coolant test.
For all we know it could generate too much noise and the OP might not want that.

Noise is a concern, but I still have two open channels on my fan controller. I dont mind noise I just want to control it if my pc is just sitting there.

Do my fans just not move enough air or is it also velocity? What would have been some good fans to run? I have thought about adding another set of fans to the top of my rads, it easy to get to and wouldnt take much to make it work.

First off we need to do a coolant test to see what is your true delta.
A Coolant test means u take your water temperature and compare it to the air temperature thats coming into your rads.

This delta represents what i said was called ground zero. There are many ways to do this if you dont have a inline probe.

If your rad capacity is indeed limited then...

The problem is in your stack.

Unless you can get enough air to your second rad, you will starve it off 2 MCR320's.

There are 3 ways to fix this.

1. You can put another set of fans ontop of your rad like the person recomended, and do whats called a push/pull on the top rad.
This would indeed give you some benifits, but could double your noise.

2. Get a thicker set of fans in the middle. Which means more powerful fans, and that will also lead to increased noise.
I have a simular stack with San Aces on Shrouds...

3. Add another layer of fan on the bottom and then again on the top (exactly what the person recommended).
So you would have a total of 9 fans.
This will allow you to "cheat" static, and hence you could downvolt them all to a comfortable level, maybe...
Well 9 fans is a lot of noise, i dont know if there is a comfortable level.

But you would have one thick stack.

Naekuh, you cannot post any more photos until you sign up and complete an amateur photography class at the local Community College. Oh yeah, and buy a can of compressed air already.

Jonni Nitro · 09-26-2009, 10:54 PM

This is sorta of a dumb question, but all my fans should match correct? If I went with a higher cfm fan on top my rads now I am sure it would have a wierd effect on the other fans.

zeropluszero · 09-27-2009, 02:01 AM

i would think that you would. i wouldnt go push/pull with different rated fans.
