i7 930 + X58 blocks, GTX360 still getting 80's temps

[Camaroz06]

Hello All,

Maybe I am expecting too much but I am a bit disappointed with the performance of a HK3.0 + GTX360 for a i7 930 @ 4ghz (1.43v). Here is the temporary loop:

Res -> MPC355 x 2 with dual EK top (later I am adding 2x220mcr's and 2xGTX480 blocks) -> HK 3.0 -> EK X58 blocks (standard x58) -> GTX 360 -> res

When running linx I am seeing 85ish degrees on the CPU and mid 60's on the vregs. I was seeing the same temperatures on my Venomous X.

I am not seeing any bubbles so I assuming the loop is bled pretty well.

Am I expecting too much? Could it have been yesterdays temps? Yesterday was in the high 70's low 80'sF. Could it be the fans? I am running GT1850's, I thought they would blow harder then they do I didnt feel too much air being moved.

are you running the fans in push or pull?

Do you really need 1.43v to get to 4Ghz - raising voltage really adds a lot of heat?

Not seeing bubbles in the tubing doesn't mean you don't have a giant air pocket in the radiator. Does the air coming out of your radiator feel warm?

Tilt your case around while the pump is on to see if there's an air pocket in your radiator... keep in mind you don't want the pump to suck air out of the reservoir when you do it.

Do you have your CPU block hooked up correctly as far as inlet and outlet?

Pictures are worth more than a thousand words.

Concur. Dude, 1.43v is seriously high for a 4ghz OC. I'm hitting <1.3v on a 920 for 4ghz. And yes, NPNT (no picture no talk).

place your hand on the bottom of the radiator (assuming barbs are on the bottom - meaning you did not install the rad upside down). If that area is warm then you probably have a good part of the rad filled with air.

[Camaroz06]

I should have the inlet correct, I have tubing setup so the middle hole on the HK is being fed. Sadly 1.43 is need to hit 4 ghz stable, I get nothing but crappy i7's.

fans are in pull config right now, until I get some GTX480 waterblocks, to prevent the hot air from blowing into the intakes of the gtx480's. Rad seems warm evenly all around. I installed the rad with barbs up.

If you're feeding your radiator with warm air from the case (meaning it's not pulling air from outside the case), then that could explain a lot. Have the radiator pull air from outside the case and see if that changes anything.

[MpG]

That is a little odd, all things considered. Although the combination of a poor mount, hot-case air and hot ambient air could account for a surprising number of those degrees. Have you tried remounting the block a few times? Not uncommon to see variances of a few degrees, just with that, even when the mounter is experienced.

Also, what case and layout? It sounds like you have both the radiator and GPU's exhausting, so how is air coming into the case? The components can't exhaust air that doesn't enter the case in the first place.

[Camaroz06]

Forgot to mention this is setup in a DD torture rack.

Air pulling through the rad seems to be room temp. Ill post some pics later when I get home.

I really think its the vcore that is causing all that heat. Did you manually set the vcore or you left the mobo on auto? The mobo will push more voltage... alot more then your chip needs. If it is set on auto... manually set to the lowest stable setting.

I highly doubt its the vcore, i have my 930 running @ 4.4ghz on air , load temps hit around 68c..

At what voltage?

[Camaroz06]

Here are some quick pictures:




The vcore does have to be that high to get to a stable 4ghz, anything else and a test (be it linx, small fft, or large fft) will crash the system well under 24h.

[Conumdrum]

Well watercooling isn't a miriacal. Methinks your Vcore is just too high, you got a bad chip. Try reseating the block again? Not much else I can say.

Does it jump to 80C like right away and stay there after 30 min? If it's lower at 70C or so and slowly climbs, then your fans are too weak. You DO have a rad that loves HS fans. Check Martins and Skinnees setup for that rad and it's heatload with the Yate Loons at 1800 RPM. Methinks your DT should be fine like it is.

Yeah, But I was expecting a larger difference between what I got on air and what I am getting for temps now. At most, with similar room temps, I am only getting a 2-4 degree drop. I'll try re-seating tonight.

Did you remove the plastic from the bottom of the block?

Proper mounting pressure on the block?

I would also take the rad off and twist it around just to make sure the air is all gone.

As good as 1850rpm GT's are, I'd consider them bottom of the food chain for a GTX and wouldn't even consider them for a GTS. If they're not at full speed, that's part of your problem.

@Camaroz06
I thing you're doing somthing realy wrong there,else you should get 4ghz @ lower vcore...Try to re-check your OC settings,I hope you should find the solution for vcore...
for 1.43vcore tose temps normal...
and gtx needs high rpm fans to show its potential.belove 1700 rpm ıts sucks(you sad that rad was warm)

[Camaroz06]

Ok Update,

I put some older scythe fans I had sitting around (forget the RPM) and turned them to push through the rad, after 1 hour 16mins of linx Im sitting at mid 70's (75-77) now down from 88 degrees highest from previous testing. Looking better now, I guess I can try to lower vcore a tick and test further.

[ottoyu34]

Interesting, glad it's improved. what fans were those and I think you need to work out the OC before fixing this with the cooling.

[Johnny87au]

at what voltage?

1.37

Waterlogged is dead on about the Fans you have chosen for that Rad.
