Cooling Aquagrafx 7800 temps!!!

Hello!

My first post on this forum...

I have noticed that there are a lot of Aquacomputer fans on this forum,,,Now a question!

Im wondering if anyone could verify my temps on my 7800gtx card with a Aquagrafx7800 cooler are resonable?

have a sli config where the aquacomputer block is the first one (Temps idle 40c Ingame 58c)
the next card is using Innovateks 7800gtx cooler (Temps Idle 41c Ingame 46c)

Is the Aquagrafx cooler that much worse than the Innovatek part?? that its constantly over 10c over the Innovatek or have I gotten a bad part?

Would appriciate if anyone could verify my temps.

 

I'd make sure the area around the core is tightened down enough. The block design between the two is fairly similar, so there shouldn't be that much of a difference.

 

the only diffrence that i can think of is that the aquacomputer blocks have floating cores, and a single pass design. Were as the innovatek blocks have a lot more mounting presure they also have muliple channels leading the the core which is bigger than the aquacomputer floating cores, so i presume there able to dispensate more heat.

 

58 is a bit too high, make sure the core is in good contact with the GPU, but do not over tighten it, i killed one GTX last week that way

 

Sorry about your GTX card... and thank U all for your input on this matter..
Will try to reinstall the heatsink again to make shure there are good contact...

I will report back if my temps gets better...

 

What size of radiator are you using?

Obviously, those temps are to be expected if your running a BIX.1

 

My loop ...

Pump-BlackIceExtreme1-CPU-Aquagrafx7800-NF4Chip-Innovatek7800-BlackIcePro1-Pump.

Whats strange is that the Innovatek could be that much cooler (than Aquagrafx)... after getting hot water from both the Aquagrafx and the NF4 Chip..

My FX-55 Idles at 30c and hits 45c ingame... so I dont think I have problems with cooling the water

 

On a single BIX1 those are very good temps... I would be inclined to say that the Innovatek block is just a better block. However, you do have to make sure on the mounting.

 

7800GTX @ 490/1350 using an AC block is running around 48 load and 30's idle.

System:

X2 4400+ @ 2.6ghz
2gb Corsair
1x7800GTX @ 490/1350

Loop:

AC Aquastream->AC Cuplex XT->AC 7800 Block->AC Airplex 360->AC Aquatube

If i turn the rad fans up then this drops dramatically but I run them on the minimum so that they just about spin and are silent

 

Mine is Delphi -> Alphacool CAPE -> Alphacool 7800 block -> XSPC 120.2 -> REs. CPU @ 270 HTT vcore 1.56 idle 31 load 40, 7800GTX 524/1389 idle 32 load 38-40. fan @ minimum

 

Hmmm .. . refitted the block but Im getting the same temps.. constantly 10c over my Innovatek block.
..this aint gonna fly!! Ím dissapointed of the Aquagrafx block... it look soo good but not a top performer obviously!

Think I will order a new Innovatek block.. I saw that they have released the new 7800 block with Voltage Regulator cooler.. Also think I will take this oppertunity to move my system into a larger V2000B case. Make 2 different water loops,, CPU and NF4 chip in one and the 2x7800gtx sli with Innovatek coolers in the other

And thanks for all your input on this question of mine! much appreciated

 

Hmmm, looks like my internal dispute-- AC vs innovatek is settled, and this is going straight over to the Soylent Green project thread

 

Does a bigger rad make that much difference? Never really looked at either of those blocks, but I have a Danger Den NV78 and a BIXIII and it never, ever goes above 38 degrees under full load, and that's overclocked to 539/1400 as well. The only difference is I have a bigger rad. I've always heard people say that my BIXIII was overkill, but if that's what I get from it, I'm pleased I went for overkill tbh.

 

Thanks for making us aware of this interesting comparison between the two blocks! Useful to know.

 

perhaps you should try using a 3rd party temperature probe to measure the temps before deciding one way or the other? The on-card probe may be sketchy.

 

For some comparison, im using two modded innovatek nv-40(6800) coolers
on my 7800's



1/4" loop consists of a fass(res) - aquastream - bip3 - nforce 4 chippy - 7800gtx - 7800gtx - mobo mosfets - fx-57. The highest if ever seen the cards go in game is 41,

 

dam those are some nice temps.. the ac blocks are somewhat disapointing.. on my 6800 the temps (with the ac 6800 block) are around 50 :/ (water temp - 18 degrees)

 

Sweet.

(BTW Sc4mpi, the reason why my MSN hasn't responded to your adding my address yet is because I hardly ever use the thing... too distracting when I'm trying to work. I'll get on it tonight...)

 

the rest of the info on my other loop if you are intrested.

1/8" loop consists of, Fass(res) - aquastream - gtx 1 mosfets, - gtx 2 mosfets - ram 1 - ram 2 - bip2 - hd1 - hd2 - hd3,

Its not true dual loop, they share a comman res , which makes filling a doddle, but it just split up the 1/4" blocks from the 1/8" so the flow rate remained good

I think the aquacomputer blocks seem to more about "bling" than performance. well thats what i seem to have experienced.

 

Just a thought:

Try swapping the blocks around between the two GPUs. See if the high temp follows the waterblock, or stays with the graphic card. Its a way to confirm that the aquagrafx is the problem. If the high temp is reported by the other GPU, then yes the waterblock is seriuosly underperforming. But if switching the blocks doesn't change which GPU is having higher heat, then either that particular GPU is having a problem or reporting wrong temps.
