Temp issues

[Brett_Bst]

Hi all, today I changed my fans round and setup so I can control the AIO fans useing asus software, AIO fans are run via the CPU header, rear fan off header 2 and front fans off header 1, I use the H115i and pump was set to 100%, now I was getting 25c idle and 70c under load @4.8ghz with 1.325v but when I turn on the system the fans are going like a jet and the cpu temp is 80c idle, is the issue the pump ? I didn't remove h115i from the cpu but I'm woundering if no wing the rad has messed up the paste or somethink ? Do I un hook everythink and re do it ? Also does the single wire fan connector on the h115i only moniter pump speed ? I will look for the manual, any help would be great as to what to try first ?

most likely the thermal paste is messed up

Ok I will have a look at that first then I think

cleaned and re mounted and still in the 90c idle, fml

In your description you didn't mention where the AIO header is connected to.

[strat guy]

"fans going like a jet" and idling at 90 ? pretty sure its a dead pump.

This makes me think you didn't replug the pump power. The fan conenctor coming off the AIO is to power it....you MUST plug it in.

[strat guy]

HWMonitor can detect your Corsair AIO pump speed (might be motherboard dependant, not sure)

[For Science!]

 

Also, don't want to rain on your parade, but the fans will behave better if you left it at the original configuration. You definitely don't want to plug your AIO fans into the motherboard especially with a 7700K + ASUS board. The ASUS BIOS at the moment has a critical temperature of 75 degrees on the CPU temp, and will force any fan connected to a header controlled by the CPU temperature up to 100% if your CPU reaches that temp.

 

It is not unusual for the 7700K to hit those temperatures, so your fans are being ramped to 100% by the motherboard. With the H100i v2, there are fan connectors on the pump itself and the fan speed is controlled by the water temperature instead of the CPU temp (in watercooling, no sense to increase the fan speed if the water is not hot).

 

If by Y-splitter you mean the splitter coming off the pump, then you need to set the fan curve of the header to max power on DC mode (100% all the time) so that the H100i v2's pump would actually spin. Then you can setup your fan curve in corsair link, linking it to the temperature read by the H100iv2's water temperature.

I dont think there is a separate header to power the pump, at least the H100 iV2 has just 2 cables going off the cpu block/pump, a fan splitter cable and a 'cpu fan' header (without which the fans wouldn't power on anyway).

Yes, and the OP has been asking whether the "single fan connector" (i.e. not the Y-splitter) is only to monitor the pump rpm, which to me implies that s/he thinks its unneccessary. Which could me an the pump is completely unpowered. Where exactly OP thinks the pump is receiving power in this situation, I don't know. If you look at the Opening post, OP describes that he has directly plugged the AIO fans to the motherboard, and some more headers for case fans, but does not mention the AIO fan header, meaning its probably just hanging loose. Lets hope not, but to me it sounds like it just needs to be re-plugged.

Okay actually I think I've made this mistake before, but the H115i should have a SATA power supply cable coming off it. This is plugged in too right?

[Brett_Bst]

The H115i has a single wired fan conector(meaning the connector onloy has 1 wire in the connector), a USB connector and a sata connector. The sata connection that runs to the power supply the 4 wire fan splitter connection all from the pump/heatsink. If I unplug the fans you can hear the pump a little aswell

The pump is powered through the sata and controlled via the USB link sofweresoftware

My apologies about the confusion surrounding pump powering (Although my other post about connecting fans to the motherboard still holds true). It is possible you just have an airlock in the pump during the installtion/reinstallion. Have you tried shaking the pump header/computer to make sure any air bubbles move up and out of the CPU block.

Nope, just the fan splitter cable and one that plugs into your mobo cpu fan pinout just like any other cooler, aio or tower/stock heatsink.

 

think OP needs to know that he can still use the Asus FanXpert or whatever software without having to plug the 2 of them in directly to the board, it just reads it as one fan but with an AIO do you really need to control the 2 fans separately ? makes no sense..

[strat guy]

also, no idea aboout the 115 (280mm) corsair cooler in question, I know/spoke only of the 100i V2 240mm one

See I thought this aswell and was woundering the chances of getting an airlock in the pump ?

What OP is trying to do makes sense. ASUS FanXpert will only let you control the pump speed for a H100iv2 through voltage regulation, not the best idea anyway. The fans are controlled exclusively through the built in firmware of the pump.

Judging from the posts i've seen on this forum, fairly common. Either just shake the bejeezus out of your case as is, or unmount the cpu block and shake it out by itself. Or simply tilting the case while its running can sometimes be sufficient.

 

Now that you've established to me that your pump is indeed running, then probably something like this will fix it. (Hopefully)

Right, much different to the 240mm one with the sata power etc.

 

I set the pump profile in Corsair Link and use fanXpert to set a fan curve. HWMonitor confirms it's using my corsair link pump profile and the asus software fan curves, but this is a whole different cooler in question so..

How bout you follow the aio directions and go from there you are better off with corsair link and set the temp monitored to the water instead of the package or die temps works like a charm

[Brett_Bst]

ok soo after all the comments i think it has an air lock or bubbles in the loop, after tilting the pc the temp went from 88c down to 65c then down after some more moving it about, right now its at 28c I was so worried I meessed somethink up lol will leave it as is for a while and see wha happens, got to love this fourm for pc issues  thanks all you all were a great help, I would have been there for hours trying to see why it was not working correct, my heart can carry on beating now lol

ok so run prime95, I have run realbench and aida64 for about 45 mins each and so far temps are 69c MAX @4.8Ghz 1.280v(1.280v - 1.300v) so all seems good so far

Nice recovery another win!
