Water cooling temps are the same as air cooled temps?

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

This has to be something environmental in your system - I just can't see how 3 different pumps would suddenly fail like this, and on top of that, they are widely considered to be some of the best pumps out there. Looking at your Twitter photo (assuming that=you), I just want to validate your loop flow order just so we can use that as a jumping off point to see if that has anything to do with anything.

OK, so here goes...

1. Pump outlet is on the top/side that runs up into the radiator on the top?
2. Radiator outlet goes to CPU block
3. CPU block goes to T-fitting, one is drain, other enters the cylinder reservoir.
4. Cylinder res feeds pump inlet (center) port

This is a straight molex or sata power connection for your pump, right? (just to re-confirm) Not powering off any PWM headers or anything?

No I didn't rinse out the sys prep stuff. It said said you don't have to rinse it out that it is safe in the instructions I'm exhausted Imma try it on another PSU tomorrow or over the weekend.

Loop order:
-Res --> pump inlet (which is facing up.) coolant going straight down into inlet of pump.
- pump outlet(which is on the side) --> rad in [tube going up]
- rad out --> CPU inlet
- CPU outlet --> T valve [ which has drain valve attach to it]
- T vavle --> Res outlet.

The pump only has red and black wires on it that has just a molex connection at the end.

That's really weird. If you have a local shop that you can buy a pump from try a different brand altogether even though all d5 pumps are the same maybe they just got a bad batch. Also only have the pump in that power line. Nothing else. I'm at a loss here.

Yea I think I've tried everything.. It's more likely looking like those Swiftech pumps are very defective. 3 in a row I can't believe this. Wasted so much money and I never got the pump to work for more than 24hrs. I really don't know what to do or say right now.

I contacted performance pcs and they said they wanna test the pump so I will ship it back to them tomorrow. I am back on air cooling now and everything in my system works fine fans, psu, gpu, cpu hdd, everything. I really think i'm getting back or faulty pumps. I wanna believe its my fault or my cpu fault but there is no evidence that points to it. Only thing that is consistent is that I installed the pumps and they run fine for a few hrs then either stop running while my cpu is on or stop working when I turn off and on my system.

ok performance pcs tested out the pump and they said it worked fine when they received it. He said he tested it with a simple loop of the pump, res and a coolant solution that they have. He tested out different speed on the pump as well and it worked fine w/o a hiccup. So weird.

So right now the one thing for sure it proved was that the pump works.
I don't think its there is a problem with my PSU as well.
I am left with something in my computer environment or my other water cooling parts.

Any thoughts?

yea imma try everything. I requested the same pump that they tested back and I bought another reservoir [xspc single bay 5.25 acrylic reservoir] and another rad [xspc ex120 radiator] to make sure it isn't any other water cooling part that causing it to not power on. I also be installing the water cooling on my brothers PC first to see if everything works fine. I should be getting the pump back on monday.

Ok I got the pump back. Tested it and it worked!!. I tested it on my brother PSU first. Then on mine. Works fine. I only used the pump with my new reservoir (xspc single bay acrylic res] and new radiator [xspc ex120 rad]. With my old existing cpu block [xspc raystorm]. Its been runnning for a day now and no issues. Imma let it run for 2 days straight to see if the pump turns off or acts strange. So far so good tho!

I suspect that xspc photon 170 tube reservoir reservoir causing the pump to shut off. Don't ask me why I don't have proof yet but i so far the pump is still running with the new res. Imma enjoy this water cooling for a while. I'll let it run for a week straight then imma test out that xspc photon res to see if the pump stops. Pics will follow and I will keep you guys updated
