Water cooling temps are the same as air cooled temps?

[jbmbk12]

Hey guys i just reinstalled my water cooling loop.
My XSPC X20 750 res/pump combo died about a year ago
and I decided to get back in the water cooling game with the
XSPC Photon 170 and a separate D5 Swiftech MCP655 pump which I
purchased from performance-pcs.com


So I installed my loop and notice
that i'm getting around the 39-42C for the
CPU temp on idle which was around the same temps I was getting on air cooling

Did I do something wrong?
Do I need a better CPU block or bigger radiator?
My main goal is to over clock this CPU

Any suggestions to improve temps please let me know.
BTW my room temp is around 80F or 26.6C



Case: Corsair 600T
CPU Intel i7-2600K
GPU: Nvidia GTX 1080
RAM: Corsair Venegeance (4x4GB) 16GB
PSU: Cooler Master V1000 80 Gold

Water cooling parts:
XSPC Raystorm 750 EX240 Extreme Kit
CPU Block: XSPC Raystorm CPU block
Radiator: XSPC EX240 240mm radiator
Pump: Swiftech MCP655-B D5 pump with speed control.
Reservoir: XSPC Photon 170 tube reservoir

I have no idea on that. Im not familiar with it. You would need to look on xspc's website for pump tops to attach pump to res. Them being seperate is kinda nice also because the pump res combo takes up some space which makes it harder to place in the case.

 

[jbmbk12]

yea that was another reasons why i decided to get them separate. Its crazy how 2 pumps failed. For some reason I dont think I should try another one of the same pumps

 

[azzazel_99]

all d5 pumps are the same regardless of who's name is on it. I would recommend a manually speed controlled one though. The only thing that makes any sense other than just bad luck is the pumps running dry for to long before fluid gets to it.

 

[jbmbk12]

ok which one is the manual speed one again? the D5 with the red knob at the back?

 

[azzazel_99]

Yes that's called the d5 vario. All the d5's are the same literally just with each manufacturers sticker on it but they are ALL purchased from the same factory so one d5 is no different than another. The pump tops are what make it different like 1/4 fittings or barb fittings

 

[jbmbk12]

ok i gotcha

 

[azzazel_99]

and of course some are pwn and some are vario (manual speed control)

 

[jbmbk12]

ok here is the deal. Just checked out performance-pcs return policy and they do not take returns on customized items such as pumps..power supplies, chasis..etc. Also if I receive a 3rd pump and it does not work for whatever reason. I can return it but there will be a 20% restocking fee. I already have to pay $15 again to ship this pump back to swiftech and this will be my second time paying $15 to ship it out again. If the next pump is defective then I would've spent more than half the cost on shipping it back to manufacturer than it cost for this pump!

 

[azzazel_99]

If it doesn't work again maybe they got a bad batch or something?

 

[jbmbk12]

yea I hear what you are saying. I think the second pump I have now came directly from swiftech

 

[jbmbk12]

Ok so my bro just came thru and we tested the pump and it in the tub of water and it worked.... Sort of. Rinsed out all my WC components with hot water then distilled. Put everything back together with the coolant and it was working moving water and the pump was vibrating.

Turned on system to see what was up. Checked temps on idle is was 35C.
I didn't put it on load because I wanted it to run for 24hrs before stress testing the system.

Played a little bit of Street fighter 2 on Genesis emulator and check the pump and it stopped vibrating. Check temps and now it was sitting on 69C on idle. Then climbed up to 90C. Currently the system still has the water cooling part setup. I placed the pump on its back during install this time so that the inlet port was facing up and gravity will pull the water from res straight down into the pump.

Idk what to try next. This is the second pump I'm testing out. I didn't send it back to Swiftech yet.
What the hell am I doing wrong or what is defective?

[azzazel_99]

is it a pwm pump or does it have the switch on the back (vario)?

 

[azzazel_99]

oh its a vario. Hmmmm loose power connection? Only thing i can think man is a bad power connector or just bad luck and you got 2 bad pumps? Set that sumbitch to max speed and see what it does?

 

[azzazel_99]

Cant remember if you said you tried different power plugs on your power supply or not.

 

[jbmbk12]

If max speed is 5 it was always on that. I tried adjusting back and forth from 1-3 then 3-5 and back I felt a little moving like it's trying to move but nothing. Temps are hotter than the sun in this piece. Yea i tested different molex same thing. All my molex cables are functional because I test before hand with LED light with molex connector.

 

[azzazel_99]

then its just bad pumps

 

[jbmbk12]

Smh now to drains all this coolant , removing parts and reinstalling my CM212Evo for the 3rd is really getting me pissed

 

[azzazel_99]

I bet. Save the coolant though right? Sucks man i hope this new pump works for you

 

[jbmbk12]

You think getting a pump top will help? I do feel like it's a real tight fit with the G1/4 tubing to fit over the 1/2" barb that the pump comes with. Or should I just get the Swiftech with the modded G1/4 pump or the XSPC pump/res. Should I even try a new CPU block? I feel like some outside entity does not want me to finish my WC build. Is there any reason why the pumps will stop running like Is there an automatic safety cutoff mechanism installed or something

 

[jbmbk12]

Yea Imma pack this crap up and send this back to Swiftech tomorrow

 

[azzazel_99]

No they will run till they burn up. Usually only reason for failure that was is a pump ran dry. But you know water is moving through your loop when it does work so. What kind of fluid are you using? Also I would use the 1/4 fittings anyway I don't trust the barb fittings. You could just get a ek pump top or the xspc one with the 1/4 fittings then just buy a few fittings. If a 3rd pump goes bad then I would Chang out the fluid and make sure the block is passing water well as well as your radiator too.

What do you mean 1/4 fittings? Are you meaning G1/4? That is the fitting thread size; both barbs and compression fittings use these as they are the most common thread size for most watercooling components...this is different than the actual tubing ID/OD size. Also, barb and compression fittings are technically both 'barbed fittings' - it is a difference of what is used as a clamp. On barbs, you use a dedicated clamp mechanism. For compression fittings, you are using the collar of the fitting as the clamp. Most people would argue that barbs are more secure because you can be more certain that the clamp on the fitting is more secure than a compression collar.

Is the pump running....is it humming or vibrating at all on the outlet port/tubing? You should feel the pulsation of the pump moving. Did you test the pump outside of the loop at all prior to installation? I was curious if you verified if it works in an environment other than the loop so you can determine it works?

I am using XSPC ECX Ultra Concentrate Coolant.

I tested the pump outside in a couple of water bins and it worked. It just had some trouble moving water from the in to the outlet smoothly. It would only move smoothly if the pump was on its back where the inlet was facing up and water was going straight down into it. Installed the pump and component back into PC with the pump inlet facing up (since it seem to be working outside of case) Jumped it and it was pulling distilled water. Put in my white coolant and it pulled water as well. Turn on my PC just to check temps real fast temps were ok. Played some Street Fighter check temps again and they were around 90C. Pump was not vibrating nor making noise.

I tried draining about half of the coolant and flipping the power on the pump on/off while tilting and shaking my case---Nothing. No sound, no vibration, no pulling of water. Same thing that happened when I first installed this replacement pump.
