Corsair H-50

[bigbubba3]

I realize that other threads may have been make addressing this, but I am a noob, so I need as much assitance as possible.

I have a i7 870 @ 3.50 ghz

ddr3 memory @ 1600 7-9-9

Gigabyte p55-ud3 mobo

The problem is with all cores and hyper threading enabled i hit 80C plus on prime 95 in less than 10 minutes. :thumbsdown:

Overclocked to 4.00 ghz with 1 core disabled i receive the same thermal specs if that helps anyone

I am in an Nzxt Phantom case. The Pump is plugged into CPU fan, the 200mm fan is in power fan, the fan on the radiator is on system fan.

I know I must have something screwed up here, 80C just seems way to hot for liquid cooled. (i suspect radiator fan isn't turned up all the way, although i can't find it in the bios)

Also the Radiator fan is an xigmatek fan which does around 60-70 CFM.

Shoulda spent more time composing this,

Corrections:

Ddr3 @ 1600 7-9-7

At 4.0 memory is @ 1820 8-10-8 (may loosen these) also this crashed after 20 minutes of prime 95, overclock at 3.5 is rock solid stable, minus high temps

Also what is QPI and does that effect overclocking potential?

Thanks, and sorry for the screw ups.

Lastly I have replaced the stock thermal paste is cool master and that may have been a mistake...

Make sure that the pump receives a constant 12V. I dont think the pump should be connected to your CPU fan header unless you have disabled automatic control of the fan in the bios. Connect it to a system fan header rather.

 

[bigbubba3]

OK how do i find that in the BIOS

Too hot.

Replace you thermal paste with Arctic or Antec. You can buy them at Fry's. Make sure you clean the contacts.

Check your fan speed.

Try going back to default settings. Run Prime95. Check temperatures. If all is normal then raise the clock.

If all else fails get the Noctua.

Read you manual.

Make certain the pump is plugged into a 3-pin header. If it's plugged into a 4-pin it might not run at full speed consistently and correctly.

There might be other issues, but just want to make sure you've got this.

Also, is the Fan pulling air into the case, or pushing air out?

 

[bigbubba3]

Just wen't into BIOS and disabled "Smart fan Control" so now all fans plugged into mobo should be running at full speed.

I will be replacing thermal paste soon, anyone know if this is any good? http://www.newegg.com/Product/Produc...%20thermal

Pump was plugged into a 3 pin, but i switched it to see if there was any difference, dropped it 1-2 C. Question is should the radiator fan, or pump be in a 3 pin (both are 3 pin) and what should occupy the CPU slot, which is 4 pin, or does that not matter.

I may have answered my own question by disabling the fan control part.

Thanks for the help so far.

The pump needs to be running all the time, and therefore CPU_FAN is not what you want. Just to be on the completely safe side, I use an adapter to power the pump directly from power supply.

As I remember them, the H50 instructions would have you orient the fan so that it is pulling air into the case. I gather that most people opt to go the more traditional direction to push air out of the case. Doubling up the radiator fan is also popular.

Good luck

Whoops forgot to answer that question lol

200 mm fan is blowing air in, and the radiator fan is blowing out the back, for anyone familiar with the NZT Phantom

From what I read from most H50 users posts is that they do as Corsair suggests and use it to take air in. Its those that go the other way (exhaust) that seems to be the minority. I'm myself have always used them as taking air in because I have found I get better(lower) cpu temps. However it does depend on the case in question. The user can try it both ways and see what is best for their rig. That is what I would suggest to do. Also if the user can do a push/pull fan set up inside their case that would be ideal. If using just a single fan you can get better performance using a better quality fan than the one Corsair provides. I have done that myself in builds. Scythe and Noctua for example make fans that move more air and do it with less noise. It is an extra cost to the build though.

Dropped to stock, and ran Prime 95 for 2 hours. Highest temp 63C.

Corsair states they get a full 10 degrees better with a similar processor, and its overclocked. Infact compared to stock I'm getting a meager 12.5% improvement in load temps.

I will change the fan to an intake, and post results.

Thanks a ton guys.

It seems that the advantage of intake goes away when you add a second fan, at least on my system. This is why I have it going exhaust as well as my desire to keep case temps as low as possible in order to benefit the rest of the system.

Here is the deal... If you're blowing air out, you're cooling your processor with pre-heated case air. If you're sucking air in, you're cooling your processor with ambient air, and dumping the same amount of heat in to your case that you would be with a normal HSF. If proc temps are an issue, most definitely suck air in. If some other component has temp issues, *consider* flipping it. Just because that other site pretends it is an authority on everything, don't take the suggestions as gospel.

Definitely not taking anything as gospel! I've tried both approaches and have monitored CPU Temp, Motherboard Temp, and GPU temp. The second fan does much more than orientation ever could and the difference in temps when changing orientation on a 2 fan H50 was small enough for me to make it worth exhausting. For good measure, I added an intake under my CD drives

Just wanted to add my observations. As always, your results may vary!

 

[bigbubba3]

OK I just changed the position of the fan. Btw its an Ximatek and at 1500 rmp does around 60 cfm, so its moving plenty of air.

When set as an intake, temps after 10 minutes go all the way up to 70C, a 7 degree increase over when it was set as an exhaust.

The last thing I will be trying is new thermal paste.

The second fan mattering more makes sense, unless your case is really toasty inside. These systems can transfer heat to the liquid faster than the radiator can remove it from the liquid until the temperature delta between the liquid and the ambient air is large enough so that equilibrium is reached. Moving more air makes the necessary temperature difference between the liquid and ambient air smaller.

I just sent results to Corsair tech support, I might get an RMA if thermal paste doesn't help.
