Cooling DangerDen Maze4

MAZE4 v MAZE3

well, I just finished our newest cooling review, "MAZE3 versus MAZE4: DangerDen Skills on Trial". What do you think??

top class review and man is the maze 4 thin it look cool to but I am getting the white water and also planning on getting the cascade!!! God I need a new hoby!!

 

What were the ambient temps in those test?

Also the average of 30 and 28 isnt 28....its 29....Not a big thing but just something I saw

 

The high and low were instances during the 30min run, however overall, 29C was the average. Those highs and lows were hit maybe once or twice in the trials.

 

What was the ambient though?

It appears on there that the cpu temp is lower than the case temp, no? Any problems with condensation?

 

Ambient temps were recorded as stabilization temps. Basically, I just let the comp idle for 30 minutes.

Case temps however should be read with heed. As I note in the article, no case was used in this test. Instead, the test bed was set across a table. No condensation occurred however as I checked constantly in fear of it.

 

So what your saying is that the cpu was cooler than the air temp around it?

Also the ambient temp in this case would be the air temp in the room which could prove my statement above wrong

 

Yup, thats what I'm saying. Remember though, I'm using the onboard diodes and those are generally not 100% accurate. The results of my testing (MAZE4 > MAZE3) can been taking as accurate because the same diode was used the measure the CPU temps.

 

Was that on the article about the diodes? If not you may want to add that saying that its not a temp review just a comparison review....Overall nice job....

 

There is a note about the temperature readings in the article under the misc. info where I talk about OS, progs used, etc. Thanks for the props

 

Very Nicely done man!

You have a learning curve that should scare the hell out of some of the large, long established sites reveiwers.

Great job, you spec'd your system & testing methods and conditions prety well. Liked the link you included for the pump. You also took some nice pics that added info themselves & reinforced points made in the article (thickness of block bases).

 

Thanks a lot! I really appreciate the feedback you gave me last time, Blackeagle. If you look at the bottom of the article, a thank you is given

 

Oh my I'm glad you felt it was of some help.

I'm really glad to see you're going for being a accurate reveiwer, not just another one of the crowd.

 

good review, good work
i was looking for a comparison but couldnt find one.

now i need a DD4 GPU vs swiftch GPU review.

 

I guess I'm a bit late to add any constructive criticism but I had a few points for future reference -
Sorry I didn't comment earlier.


1) You should state the revision of the motherboard (and maybe whether the chip was a Palo or Tbred too).
Reason being, the GA7VRXP Rev 1.0 and 2.0 each use a different sensor type for CPU temp.

2) MBM5 is pretty much (review) industry standard for monitoring temps, MBMLog is also a very nice add-on for recording them.
I've never actually used the Gigabyte software but if it's anything like AsusProbe, pleeeeease try MBM5.
{If you do decide to use this in the future with the same board, the sensors to select are SIS950/ITE8705F 2 for the Rev 1.0 and LM83 7 [remote] for the Rev 2.0 (as taken from the MBM Motherboard list)}.

3) If the board has a remote thermistor header (JT1 usually), use a bulb probe on this to monitor the ambient surrounding air temp where it won't be affected by being in the vicinity of other components on the board and can be logged as a reference point by comparison (intake air to the rad is a good place to measure ambient from).

You can also repeat the test with a flat probe inserted under the block, near the core for further confirmation of accuracy.


4) 30 minutes is pretty short for watercooling to hit peak temps and stabilise. Personally, I tend to log for a 2 hour stretch where possible.
Did you find it had maxed out for a while at this temp? (Again, MBMLog plots a nice progress chart for you to show the rise in detail.)


5) Lapping - would you not think it better to test without (or at least before) doing this, so that people could get an idea of what to expect out of the box?
I've seen varying finishes on waterblocks in the past and obviously some blocks don't actually require lapping in the first place.

Lastly, if you want to be really thorough, get an average over three tries, not two - cuts out the chance of a rogue factor like an airlock colouring the overall results.


Other than that, nice job. Clear and concise.
Oh and I don't mean to be brutal, I just have high standards.

 

lapping the blocks took whatever good was in that review and tore it to pieces.
Also and next time use prime95 as that is the industry standard for cpu stability test and will put your cpu under more load than anything else.
Far better than before, but still room for a lot of improvement

 

It sure did max out (the temps that is). In the future, I will use MBM5 and the software you recommended for load testing. Thanks for the advice and the comments.

 

I would like to comment that in the future we have plans for much more accurate bench testing reviews, as well as more accurate system testing reviews.

Currently in development at Elite Technology is an 80W to 200W variable heat element die to mimic that of actual processor temps while still giving us an accurate heat wattage and thermal resistance determinators.

Another addition to the reviews coming soon is flow rate. We are investing in a few flow meters to see what the flow rate is before and after the waterblock to see what resistance the water block has, and with the use of a simple regulator we can use the flow meters to test each block at the same LPM therefore increasing the accuracy of a comparison.

To complete the setup, a com port thermal probing system with a few (not yet determined... more than 5) thermal probes and an application recording the results is in development to increase the accuracy of our results.

Luckily these projects may be sponsored by our school, and we will be helped by the physics department to put together all of this equipment.
